Description Emmanuel Surleau 2009-07-26 22:11:36 UTC 
Version:           c2cf251dfe808e1a4e336dbf1cddc645d63c2e2f (using KDE 4.2.96)
Compiler:          gcc version 4.3.3 (Debian 4.3.3-14) 
OS:                Linux
Installed from:    Debian testing/unstable Packages

Rekonq crashed randomly when I was browsing (and I can't seem to reproduce it at the moment). Here is the automated bug report that the KDE wizard generated:

Version of the application: 0.1.10
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.2
Operating System: Linux 2.6.30-2.slh.2-sidux-686 i686

Comment 1 Andrea Diamantini 2009-08-10 15:19:37 UTC 
Does this still happen?
Comment 2 Emmanuel Surleau 2009-08-10 21:47:04 UTC 
Haven't managed to reproduce it for now. I suppose it can be closed, at worst I'll open a new bug if it happens again.
Comment 3 Emmanuel Surleau 2009-09-23 07:10:01 UTC 
Since this bug hasn't been closed... I have another random crash issue with rekonq revision 54b2bdfcaf9bf0113f286c4b04550b75cda7ee22

This one has happened several times already, but not a reproductible fashion.

Comment 4 Andrea Diamantini 2009-10-22 16:52:15 UTC 
seems fixed. Isn't it?
Comment 5 Emmanuel Surleau 2009-10-24 23:14:25 UTC 
Hasn't happened for a while at least. Hard to tell with random crashes.
Comment 6 Andrea Diamantini 2009-11-05 11:01:55 UTC 
Ok, Closing. At least the bug causing this crash has been fixed.
