--- Comment #11 from Joshua Clayton <stillcompil...@gmail.com> --- Situation: partitioning an SD card from a script using parted. Interestingly the new partition layout is usually the same as the old partition layout I can crash plasma repeatedly with this trick. (thankfully plasma restarts) Looks like soid tries to create a QVariant for something whose name is still valid, but whose file handle has been destroyed. Application: kded5 (kded5), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
