As pointed by Coverity, in the "Configuration" panel of WPrefs there are some images loaded, but if the images cannot be loaded correctly then the returned NULL pointer can crash the application as it is dereferenced in further function calls. To solve this case, this patch is adding a NULL pointer check in the functions RScaleImage (wrlib) and WMCreatePixmapFromRImage (WINGs), so both can accept that NULL pointer to also return NULL, which means the existing check for "icon == NULL" in the WPrefs code will be useful.

WindowMaker raster graphics library This library is used to manipulate images and convert them to a format that can be displayed through the X window system. Read the wraster.h header for an idea of what is available This Library is LGPL and Copyright (c) Alfredo K. Kojima <kojima@inf.ufrgs.br> The following environment variables control some parameters: RIMAGE_CACHE <integer> Is the maximum number of images to store in the internal cache. Default is 8 RIMAGE_CACHE_SIZE <integer> Is the size of the biggest image to store in the cache. Default is 4k (64x64) Porting ======= It should be fairly easy to port it to other environments (svgalib, libggi etc), probably only requiring wraster.h, context.c and convert.c to be changed. Note that the X specific code should be disabled in that case, including support for libXpm.
