I have also crashes of plasma-desktop after login (most of the times). Sometimes a crash of plasma-desktop out of the blue.

(How can I install debugging symbols for libQtScript.so.4 ? Well that is where I have "??" in the backtrace. Or do I need to install something else? (The 'needed packages' mentioned in the "list of files" mentions "/usr/bin/plasma-desktop" _only_ .))

Comment 2 Myriam Schweingruber 2012-09-07 03:34:42 UTC 
MQ: your crash is Python related, you probably use an outdated plasmoid causing the crash.

erd_a: no idea what causes your crash, s you don't have debugging symbols at all. Please search in your package manager for -dbg packages and install those. This has probably nothing to do with QtScript anyway.
