window close unexpectedly (0.9.96 unstable)

[bulinancio]

When I build unstable version from this source:

http://screengrab.doomer.org/download/screengrab-0_9_96_/

the window close unexpectedly if you select "Type: Window" and click on "New Screen", if the main window of the app is on the Root window of the desktop screen.

However, this DOES NOT happens if I use the app from the package:

http://screengrab.doomer.org/download/screengrab_0_9_96-ubuntu1_i386/

This is the buggy log from terminal:

Whatis your distro? What is your desktop environment or window manager? And what is your Qt version? And please give me log of Screngrab building process from sources.

Distro: Debian 7.0 (wheezy) Window Manager: FVWM (version 2.6.5) Window Manager: OpenBox + Razorqt (version 0.5.2) Same behavior but if you make DOUBLE clicks on "New Screen" button. Qt version: 4.8.2

Building log for ERR and OUT togheter, using the command:

dpkg-buildpackage -us -uc -rfakeroot -b >build.log 2>&1

see: http://auil.net.br/camille/temp/build.log

Building log for ERR and OUT separated, using the command:

dpkg-buildpackage -us -uc -rfakeroot -b 2>build-err.log >build-out.log

Thanks for your build logs. I will test it in the next few days on the virtual machine in Debian and FVWM in my system (Gentoo) and try to fix.

Perhaps this is a problem on the side of the VM, since I was not able to reproduce this behavior in my KDE.

Hi, thanks for your message.

Yes, I agree that this is probably not an application's issue, but rather than a WM and/or system problem.

I guess so, because the problem appears when I build the app from sources in my PC, but do not appears when I use the binary shipped in your Debian package (.deb file).
