PVS window closes whenever trying to browse for a file

Hello,

We are working with IC618.500.29 and have PVS installed and loads fine from Layout Suite.

However, whenever hitting 'browse for file' button, PVS window closes with no error in the CIW. This happens regardless of the file we try to browse for, or the PVS tool invoked.

This doesn't happen with either Quantus or Calibre tools.

Looking at pvsUI_ipvs.log, we get the following error:

'(pvsgui:3417506): Gtk-WARNING **: 15:17:57.522: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.
**
Gtk:ERROR:gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Adwaita/16x16/status/image-missing.png: Fatal error reading PNG image file: bad parameters to zlib (gdk-pixbuf-error-quark, 0)'

I suspect it's either a permission issue, or a path setup issue, but all the recommendations online from linux forums didn't help so far.

Any assistance will be highly appreciated.

Thanks,

Matan
