getColorSpace, part of lcms, is passed a null pointer.
GfxICCBasedColorSpace::parse has this sequence of code:
if (hp == 0) {
error(errSyntaxWarning, -1, "read ICCBased color space profile error");
} else {
cmsHPROFILE dhp = (state != NULL && state->getDisplayProfile() != NULL) ?
state->getDisplayProfile() : displayProfile;
if (dhp == NULL) dhp = RGBProfile;
unsigned int cst = getCMSColorSpaceType(cmsGetColorSpace(hp));
unsigned int dNChannels = getCMSNChannels(cmsGetColorSpace(dhp));
unsigned int dcst = getCMSColorSpaceType(cmsGetColorSpace(dhp));
hp can't be null, or else we wouldn't be calling cmsGetColorSpace.
This means dhp must be NULL, which can only happen if RGBProfile is
null.
RGBProfile is set up in GfxColorSpace::setupColorProfiles(). Assuming
this function has been called, it does the following:
RGBProfile = loadColorProfile("RGB.icc");
if (RGBProfile == NULL) {
/* use built in sRGB profile */
RGBProfile = cmsCreate_sRGBProfile();
}
cmsCreate_sRGBProfile can return NULL in a number of ways.
I'm not sure what the fix is though.
