Description of problem: I did not reproduce this bug for LXDE and MATE, but issue is present for KDE and depends on initial size of window before creating new project.


Version-Release number of selected component (if applicable): tupi-0.2-1.git04.5.mga5.i586.rpm


How reproducible: KDE: always for small window and not often for maximized window


Steps to Reproduce:
1. run tupi in KDE
2. change size of window less
3. File -> New project -> OK

[user@localhost ~]$ LC_ALL=C tupi
