Debian Squeeze with KDE 4.1.4 from backports..

just the subject
1) added links to download
2) kget crashed (after some random time)
3) launched kget
4) go to (2)

it does not crash if only to download 1 file per time.

p.s. it just works and then crashes, without even touching it
p.p.s. in Debian Lenny it was the same

If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? 
You may need to install the "kdenetwork-dbg" package
Thanks :)
Comment 2 Perpetuum_Mobile 2009-03-05 00:44:00 UTC
ok, now, some news're here:
this time it has come in such way -
1) added one download (using right mouse button click on kget icon in "systray" - "new download")
2) while it was running, added one more (same way)
3) while they were running, clicked with right mouse button on icon of kget in "systray"
4) icon disappeared and window of kget crash analyzer appeared instead...
so, here is the backtrace report (kdenetwork-dbg had been installed):

Comment 3 Perpetuum_Mobile 2009-03-05 00:48:39 UTC
this time i just launched kget again and really did not do nothing else (any move or click) and after some seconds it crashed again (with that 2 downloads, described in previous message):
