I have a similar problem here - i wanted to use the Store button to launch KTerm.
I added it to the database using the SQLite3 prompt:
INSERT INTO "handlerIds" VALUES('com.lab126.kterm');
INSERT INTO "properties" VALUES('com.lab126.kterm','command','/bin/sh /mnt/us/extensions/kterm/bin/kterm.sh');
I then changed the store button action to com.lab126.kterm: it now successfuly launched KTerm, but a few seconds after it launches, i get a dialog saying "Application Error: The selected application could not be started. Please try again". In the system log, i get the same error as bhaak :
140222:143540 appmgrd: W appmgr_history:timeout_check:lipc_id=com.lab126.kterm,state=EXECUTED:Timed out waiting for app to register a lipc id
Is it possible to get rid of the error dialog?
Thank you very much
