Description Denis Silakov 2013-01-22 11:38:06 MSK

There was a long thread in the MIB forum and other places about rpmdrake crashing in some situations:
http://mib.pianetalinux.org/forum/viewtopic.php?f=54&t=3668&start=20

It turned out that such crashes arise when rpmdrake attempts to flush its UI - a feature that was added very long ago, as a workaround for Gtk deficiency due to which rpmdrake windows were not redrawn automatically in some cases (https://qa.mandriva.com/show_bug.cgi?id=15408).

However, it seems that there is no need in such forced UI flushing with modern GTK. It only introduces problems.

There was also a long discussion in Mageia that led to the same decision:

Comment 1 Denis Silakov 2013-01-22 11:41:24 MSK

Advisory:

Disable obsolete UI flushing in rpmdrake that could lead to crashes.

Build lists:
https://abf.rosalinux.ru/build_lists/900614
https://abf.rosalinux.ru/build_lists/900615

Note that it can be hard to reproduce the actual bug (discussed in Mageia bugzilla or MIB forums). Some of us managed to reproduce the bug only when starting rpmdrake from console, others cannot reproduce the bug at all...

Original reporters from MIB say that this fix doea eliminate the problem.

However, it would be nice to additionally test rpmdrake at to check that at least the problem described in https://qa.mandriva.com/show_bug.cgi?id=15408 doesn't appear again.

I reproduce the bug on i586 and x64 ROSA
1) Run rpmdrake from konsole.
2) Install inkscape
3) When installation continue, 3-4 times overlap dpmdrake window by other window and restore it's focus.
