[stand-by] Image viewer cashes Wings3D on Linux

[micheus]

It was checked by Phill92 and nigec the problem they are reporting has the same origin - it comes from the X Windows system (from Linux) in accord with the error message we could to track:

Code:

The program 'Erlang' received an X Window System error.

This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
(Details: serial 32752 error_code 9 request_code 62 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

It's in a OS service used by Wings3D which we have not way to get more information without to debug that module since the linux used by dgud doesn't has this problem (I don't have a working linux install to check).

This way, I'm going to state this thread as in "stand by" hopping someone else can try to figure this out.
