http://bugzilla.opensuse.org/show_bug.cgi?id=904446 --- Comment #6 from Kenneth Ingham --- According to the digikam maintainer, this is a bug in libexiv2: https://bugs.kde.org/show_bug.cgi?id=341024 However, the libexiv2 people say that this is the expected behavior and the bug is in digikam: http://dev.exiv2.org/issues/997#change-2963 This last report also says that digikam does *not* crash on these files. This implies that there is a fix upstream. Any chance of getting this fix into OpenSUSE? I can compile from source, but that comes with its own pile of problems. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=904446 --- Comment #8 from Kenneth Ingham --- Additional info. I removed all repositories other than official 13.2 repositories and KDE:Extra for 13.2, did zypper dup, and rebooted. The bug still exists. digikam comes up and crashes almost immediately, making it unusable. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=904446 --- Comment #10 from Kenneth Ingham --- I raised the upstream bug and they say that it is fixed in upstream sources. See: http://dev.exiv2.org/issues/997 -- You are receiving this mail because: You are on the CC list for the bug.

There I have libexiv2-13 version 0.24 and libkexiv2-11 from KDE 4.14.3. I cleaned out all digikam config and database files, so that I would have a clean starting point. I copied a couple of mp3 files and your XCF file in my pictures-folder and started digikam. It did not crash, but gave the following output (as that I started it from a konsole): raymond@HQVMT44011:~/Pictures% digikam digikam(27696)/KEXIV2: Cannot load metadata from file (Error # 11 : /home/raymond/Pictures/130bpm_funktastic_voyage.mp3: The file contains data of an unknown image type digikam(27696)/KEXIV2: Cannot load metadata from file (Error # 11 : /home/raymond/Pictures/waterfall-1355.xcf: The file contains data of an unknown image type digikam(27696)/digikam (core) Digikam::ThumbnailCreator::createThumbnail: Cannot create thumbnail for "/home/raymond/Pictures/130bpm_funktastic_voyage.mp3" digikam(27696)/digikam (core) Digikam::ThumbnailCreator::load: Thumbnail is null for "/home/raymond/Pictures/130bpm_funktastic_voyage.mp3" digikam(27696)/KEXIV2: Cannot load metadata from file (Error # 11 : /home/raymond/Pictures/waterfall-1355.xcf: The file contains data of an unknown image type digikam(27696)/KEXIV2: Cannot load metadata using Exiv2 (Error # 11 : /home/raymond/Pictures/waterfall-1355.xcf: The file contains data of an unknown image type So these are the exceptions that Gilles was indicating which libkexiv seem to catch and just outputs them as debug output.

If comment#30 is still about libkexiv crashing, then this is a very change crash as that now XCB seems to be involved.

But it would be better to raise this on bugs.kde.org together with the crash report as that it seems a different bug than before.

See this upstream bug: https://bugs.kde.org/show_bug.cgi?id=342010 That explains part of my problem, but not all of it. Digikam still crashes all the time, even after I dealt with the xcb issue. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=904446 --- Comment #47 from Kenneth Ingham --- I have (finally) resolved the problem. The root cause is a crash in xcb caused by KDebug calls in a thread where it should not be. The way to work around the problem is to run kdebugdialog --fullmode and make sure that nothing with Digikam or KEXIV2 has "Message Box" selected. The upstream developers say that KDE 5 properly resolves the problem because qDebug is thread-safe. -- You are receiving this mail because: You are on the CC list for the bug.
