This needs some HTTP-based inst-repositories (Add-Ons). That's why I switched several packages not to install from DVD but from remote repository, when the last switching killed YaST :( -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

...

As Qt work in threads I just might have been too fast when selecting one package by another and switching the repository to install from.

Thread usage in the UI does something completely different from what you obviously think it does. While the package selector is open, the other thread (the YCP thread) is waiting for that Qt thread to finish. Nothing is done in parallel. Otherwise, we'd be in memory corruption hell all the time -- everywhere, not just in the package selector. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But that can't be the case for several reasons: For one thing, the crash happened in the first instance of the YQPackageSelector (that's where the YQPkgSelMapper might be used), for another, it is only used in YQPkgPatchFilterView.cc and in YQPkgUpdateProblemFilterView.cc, none of which are relevant or even just used here. So we can exclude this problem sceanario. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
