Description Thomas Freitag 2015-07-06 11:36:05 UTC 
In SplashOutputDev::unsetSoftMaskFromImageMask the maskBitmap is reset to NULL. So if a PDF has nested softmasks, the inner one resets it and the outer one uses then the null pointer which results in a crash.

My sample bitmap is to huge and not public, therefore is send it in private.
