Application: rekonq (0.4.68)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I was browsing rekonq bugs on bugs.kde.org, while I was reading a bug about rekonq eating "&" signs on tab labels, I opened a example tab in the background, this crashed rekonq.

 -- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault

http://www.pg.com/de_DE/ this was the page I opened.

Comment 2 Panagiotis Papadopoulos 2010-05-17 16:34:22 UTC

it does not crash here with rekonq 0.4.68 and Qt 4.6.2 (Arch Linux)

> it does not crash here with rekonq 0.4.68 and Qt 4.6.2 (Arch Linux)

I would like to add a bit more information:
I was browsing rekonq bugs on bugs.kde.org, while I was reading a bug about
rekonq eating "&" signs on tab labels, I opened a example tab in the
background, this crashed rekonq. At that time I had a total of 4 tabs open, 1 kde bugzilla search entry tab, the mentioned bugreport, a third tab, I believe it was favorites and the 4th one was http://www.pg.com/de_DE/ I opened the last one via middleclick on a link from the 2nd tab (the bug report). I remember that the page loaded, I saw the title being displayed without the "&" like mentioned in the bug report, I clicked on that tab to open it, it crashed.
Also I would like to add, that the urlbar of rekonq showed a wrong url (this was while I was in tab #2) it showed this url: http://mercurial.selenic.com/guide/ I opened that site a litle while before that in a new tab, closed it, and the second tab displayed that url from that point on.
This may or may not be useful for this bug, but at least now you know the whole truth :D

Comment 4 Andrea Diamantini 2010-05-21 16:28:43 UTC

works here, too. 0.4.70

> works here, too. 0.4.70

With all due respect, just because you can not instantly reproduce this crash, doesnt mean it doesnt exist. As I mentioned, this is not a report "rekonq crashes every time I visit site xy", this is more a report about a crash that may happen only when another bug occurs.
The crash was reported from rekonq 0.4.68, thus it is most likely still present in current git, reopening.

Comment 6 Andrea Diamantini 2010-05-22 09:15:33 UTC

Jakob, sorry for closing it without waiting any reply. But I usually tend to close bugs against 0.4.68 (a bugged number) that neither me or pano (first 2 rekonq users) cannot reproduce.
Consider also I stay about 8 hours a day with rekonq opened on my desktop (and every time with last code pushed). This bug never happened here.

Please, try to better explain what are the steps to do to reproduce it. Opening/closing/reopening tabs with the site suggested opened in back/top ground doesn't lead to a crash, here (worksforme).

Regards,

Comment 7 Panagiotis Papadopoulos 2010-06-06 19:14:44 UTC

still works for me…
