Crash on starting Camera Configuration

[dstaubsauger]

When I click on "Configuration" → "Camera...", sitplus crashes with the following error:

(sitplus:15662): Gtk-CRITICAL **: IA__gtk_window_resize: assertion `width > 0' failed

Status changed to 'Confirmed' because the bug affects multiple users.

The same happens to me when using eviacam

Regarding SITPLUS, it seems that opencv is missing in the list of dependencies of the package:

Depends: libbluetooth3 (>= 4.91), libboost-filesystem1.49.0 (>= 1.49.0-1), libboost-program-options1.49.0 (>= 1.49.0-1), libboost-system1.49.0 (>= 1.49.0-1), libboost-thread1.49.0 (>= 1.49.0-1), libc6 (>= 2.15), libconfig9, libgcc1 (>= 1:4.1.1), libpocofoundation9, libpocoxml9, libportmidi0, libsdl-gfx1.2-4 (>= 2.0.22), libsdl-image1.2 (>= 1.2.10), libsdl1.2debian (>= 1.2.10-1), libstdc++6 (>= 4.6), libv4l-0 (>= 0.5.0), libwxbase2.8-0 (>= 2.8.12.1), libwxgtk2.8-0 (>= 2.8.12.1), libx11-6, libxtst6, sitplus-data, pd-cyclone, pd-freeverb, pd-iemnet, puredata, pd-libdir, pd-list-abs

Also missing in the affected library:

$ ldd /usr/lib/sitplus/libmod_camera.so | grep cv
$

BTW: I just released a new version of sitplus [1]

Regarding eviacam, is not the same problem. Notice the message "Unable to find any suitable image format" which means that your camera is still not supported by eviacam. This should be resolved in upstream. Please, submit a bug report [2] indicating the webcam model you use and the relevant dmesg and lsusb output.
