Version:           3.5.7 (using KDE 3.5.7, Debian Package 4:3.5.7.dfsg.1-1 (lenny/sid))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.21-1-686

I went to http://www.puntoradio.com/10000, there I clicked right to the headphones picture in "Escuche la radio" which linked to http://www.puntoradio.com/10000/#. In the end I think it opened http://www.puntoradio.com/streaming/endirecto.php which ask me to open http://www.punto....ing/puntoradio.pls, to "save it as" or cancel...

I chose "save as..." and the konqueror crashed with this backtrace: 
Using host libthread_db library "/lib/i686/cmov/libthread_db.so.1".

Looking into the code: svn://anonsvn.kde.org/home/kde/branches/KDE/3.5/kdelibs/kparts/browserrun.cpp line 218 and using gdb I noticed that m_suggestedFilename was NULL(or invalid) but two lines before that value was used and it didn't crash there.

After some other bugs[1][2][3][4] I think maybe there could be something badly I have. Anyway I must say that I run memtest and it hadn't found any error. Other options I could think is that I use Linux suspend to disk feature, and maybe that leads to any kind of memory corruption. What do you think?
