KMyMoney failed to startup, but showed the empty outline of the "Did you know?" dialog only. After stracing the process, I've found out that it was looking for / waiting on ~/.kde/share/config/kmymoneyrc.lock. It would have been more helpful, if there was a message about this - preferably in the GUI, but even on the console output it would have helped. Reproducible: Always
The file in question is maintained by the KSharedConfig object, which is part of the base KDE classes. KMyMoney does not access (create, write, read, delete) this file and all access to the config system is encapsulated by the above mentioned KDE base object. Thus this is more of an upstream problem..
