Description Alexey Chernov 2009-02-03 23:57:39 UTC

Version:            (using KDE 4.2.0)
Compiler:          GCC 4.3.2 Target: x86_64-unknown-linux-gnu Configured with:  ../gcc-4.3.2/configure --prefix=/usr --libexecdir=/usr/lib --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --enable-languages=c,c++,fortran,objc,treelang --disable-multilib --enable-c99 --enable-long-long Thread model: posix
OS:                Linux
Installed from:    Compiled From Sources

When editing (i guess, selecting) some pasted html text Kopete crashes. To reproduce:
1. Copy and paste some html from browser to input field in conversation window.
2. try to select it, try to backspace it.
3. Kopete crashes.
For me it crashes always when i paste a couple of comments from this page: http://habrahabr.ru/blogs/im/51005/ But it's russian so must be not very useful.

Comment 2 Dario Andres 2009-02-04 20:00:00 UTC

As you are using an unstable Qt (4.5) I suppose it's a Qt bug.
Can you try later with an updated Qt snapshot? (or a future beta) ?

Comment 3 Alexey Chernov 2009-02-04 20:02:16 UTC

Yes, of course, i will try it as Qt will be updated

Comment 4 Alexey Chernov 2009-02-06 12:53:44 UTC

I've updated Qt 4.5 to RC1 last night and the crash isn't reproducible anymore. I think it can be closed.

Comment 5 Dario Andres 2009-02-06 13:02:09 UTC

Reopen if you experience it again :)

Comment 6 Alexey Chernov 2009-02-06 13:11:13 UTC

Ok. I'll test it with future Qt prereleases to 4.5

Comment 7 Alexey Chernov 2009-03-10 00:09:11 UTC

Can't reproduce for Qt 4.5 final, so it remains closed. For 4.5 it isn't there.
