Summary: LSB: Some Gtk tests fail due to Cairo rejecting 16-bit
pixmap format
Product: openSUSE 10.2
Version: Beta 1
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: P5 - None
Component: GNOME
AssignedTo: bnc-team-gnome@xxxxxxxxxxxxxxxxxxxxxx
ReportedBy: jdluhos@xxxxxxxxxx
QAContact: qa@xxxxxxx


Some tests of the LSB Gtk test suite fail with the following diagnostics
printed on the stdout:

Error: Cairo does not yet support the requested image format:
Depth: 16
Alpha mask: 0x00000000
Red mask: 0x0000003f
Green mask: 0x000007c0
Blue mask: 0x0000f800
Please file an enhacement request (quoting the above) at:
http://bugs.freedesktop.org/enter_bug.cgi?product=cairo
GtkWindow: cairo-image-surface.c:155: _cairo_format_from_pixman_format:
Assertion `NOT_REACHED' failed.

The 16-bit depth is caused by the fact that this test runs in virtual
framebuffer set to this depth; when the framebuffer is reconfigured to use 24
bits, the test passes.

I'm not sure whether Cairo is expected to support such format, so I don't know
who is in error here...
