Bug#385568: konsole may freeze himself and the current KDE desktop
Package: konsole
Version: 4:3.5.4-2
Severity: normal
trying to reproduce the bug previously reported, i randomly clicked on every button of my mouse several times.
i've run into another bug : while clicking i opened the ''rename the session'' (thing when you doubleclick a tab) but then
konsole was unresponsive, the current desktop was unresponsive too, i could move the mouse, but it was unresponsive to my
clicks
switching to another desktop using keyboard shortcut and reswitching to the faulty one, everything is normal but
konsole. focusing it make the desktop unresponsive like before
to make konsole work again, one must click the [X] close button of the dialog
while in another desktop, i've attached a gdb and issued a bt and a info all-registers (attached)
i've reproduced this bug two times, but it need several click...
so if you're bored ...
step to (try to) reproduce :
- open konsole
- try to click with very button of your mouse, mostly on the tab bar
