Description 81joe81 2006-03-27 09:55:07 UTC
Version:            (using KDE KDE 3.5.1)
Installed from:    Ubuntu Packages
OS:                Linux

I was trying to delete 6 messages in gmail (with "fake" Firefox 1.0 identification, if it could be useful) and konqueror crashed with this backtrace:

Comment 1 Maksim Orlovich 2006-10-28 22:27:08 UTC
SVN commit 599857 by orlovich:

Prevent crash-inducing recursion of detach due to blur events 
happening  when widgets with focus get destroyed, by quietly shifting
the focus to the view...(#135384, probably #124342 --- best I can tell given 
imperfect information); also affects some bugs which I separately closed as 
non-reproducible, but which involved such a sequence

Also fixes freezing in #92497, as we no longer try to find something 
to focus when nothing is focusable..

BUG:92497
BUG:124342
BUG:135384
