Running OpenSuse 11.1 beta 3. Ktorrent OpenSuse package 3.1.3 also crashes when scan folder is enabled. I build from source and same result. Immediately after clicking the Scan folder button Ktorrent crashes. Output in the terminal when launched:
ktorrent(25911)/kdeui (K*Gesture*) KAction::setGlobalShortcut: Attempt to set global shortcut for action without objectName(). Read the setGlobalShortcut() documentation.

I have experience that Ktorrent won't start if the scan folders contains torrent files.

Have you already configured the plugin with folders and does they contains files? If so, remove the torrent file start ktorrent and move the torrent files back again.

Have you got a backtrace ?

tried your idea. i went and deleted all the torrent files in the dir and i deleted all ktorrent's config files so that shouldn't be an issue. I wouldn't care if ktorrent could start torrents silently. I use ted to grab episodes and I don't want to have to be at the pc to confirm that i want to download them ...

Seeing that I can't reproduce this, no backtrace means no fix

Ooops, missed the message about backtrace. No kde crash dialog appears, so I followed instructions to use gdb. Here's the output:

I chose to stop at #200, should I post more?

No that should be enough, but It seems to be some sort of infinite recursive loop

Which scanfolder settings are you using ? And how does the directory which is being scanned look like ? Does it have subdirectories ?

I have added some safety checks which should prevent this from happening. If anybody who can reproduce this, can confirm this with latest code from SVN, please do, seeing that I have not managed to reproduce it.

well it works now. Somehow though it still had my download folder listed already so I must not have found all of ktorrent's config files. I appreciate the quick fix and love Ktorrent!
