dolphin crashed with SIGSEGV in QTabBar::mouseMoveEvent()

Binary package hint: kdebase

Description: Ubuntu 9.10
Release: 9.10

  Installed: 4:4.3.2-0ubuntu3

This always happens when I am browsing SMB sources. I can work with the smb source for a few seconds (7-10 sec) before my dolphin instance freezes. Sometimes, it will release and I can continue what I was doing after 20 seconds. Other times, it will crash.

Could you please install kdebase-dbg and try to get a backtrace of the crash from the KDE crash handler? (Testing with KDE 4.3.3 would also be appreciated: http://www.kubuntu.org/news/kde-4.3.3

[wyretrip (wyretrip)]

I installed kde 4.3.3 yesterday and will continue to test for this. So far, in the brief time I have looked at it this morning, things are looking better.

Thank you for the follow up Jonathan!

[Jonathan Thomas (echidnaman)]

Great! I'll close this, but feel free to reopen if the crash occurs again. (Preferably with a backtrace as I mentioned in my last comment.)
Thanks.
