python applications usually give a traceback when they crash,
please start the programs from the terminal and paste the output.

This the output that Picard gives indefinitely until killed:

QWidget::setMinimumSize: (/MainWindow) The largest allowed size is (16777215,16777215)

And for Flacon:

Flacon is not using GTK, is pure Qt application, stange!

Same error message for the Leo editor entered from the terminal command line with the following command.
python launchLeo.py
FYI
I tried it with and without the gtk involker, and got the same message. The command to involk gtk is as follows.
python launchLeo.py --gui=tk

This seems related to bug 1005677 which itself is a re-emergence of the old bug 805303.
Starting Flacon and Picard with LIBOVERLAY_SCROLLBAR=0 indeed seem to fix the issue.

Finally, adding LIBOVERLAY_SCROLLBAR=0 to launcher does not fix the issue.
