This is nasty one. Crash happens in the destructor of QString. 

Could you run kstars from console using command below and post output here?

$ KDE_DEBUG=yes kstars


Does kstars crash if you start it and immediately close it? Or do you need to do something to trigger crash?
Comment 2 V-nix 2011-03-18 20:40:29 UTC 
Hello,

I was trying to control the telescope mount (a Losmandy G11) with KStars, but other then using the 'Device Manager' and the INDI interface in KStars, I didn't do much. 
However, I may have shutdown KStars whilst it was still attempting to connect to the mount.

As instructed I tried the KDE_DEBUG=yes kstars command, with the following output after closing KStars again:

Hi, is this bug stil present in latest version of KDE? If yes  please send a new debug info.
Comment 4 Jasem Mutlaq 2015-01-27 16:43:49 UTC 
There were issues with the device manager a couple of years ago, all issues should be resolved by now. Closing the bug since it works for me in all conditions above with even more equipment under stress testing using the GIT version.
