Comment 1 Frank Reininghaus 2008-09-02 23:30:03 UTC

Thanks for the bug report. Unfortunately, I cannot reproduce this: I opened Konqueror (both 4.1 and today's SVN trunk), entered ftp://ftp.kde.org/ in the location bar and pressed Enter. The connection to the FTP server was established without problems.

What did you do before you tried to go to the FTP site? Did you just start Konqueror (with an empty start page?), or did you have some page open?

Comment 2 Martin Fabian Hohenberg 2008-09-03 07:22:11 UTC

Basically, i did absolutely nothing prior to connecting to an ftp host. This crash actually does exist just after loading up a fresh instance of kde4 with an konqueror showing an empty page, as well as in a well-used session with several websites and tags open.

Also, it seems to be host-independent - the crash occures on every host i've tried so far, so protocol inconsistencies are not to blame.

Comment 3 Martin Fabian Hohenberg 2008-09-06 09:22:17 UTC

Seems to no longer be valid - 4.1.1 does not show this behaviour. Probably a problem with Ubuntus libraries...

Comment 4 Frank Reininghaus 2008-09-06 11:05:18 UTC

Martin, thanks for the info! If the bug reappears, just reopen this report. I've just noticed that khtml::Cache::clear () appears in frame #8 of your backtrace, looks like the actual cause of the bug was that Konqueror tried to clear the browser cache and failed for some reason.

By the way, please close bugs with "WORKSFORME" if you can't reproduce them anymore. "FIXED" is only to be used by developers when they found out the actual cause of the bug and fixed it.
