Thanks. That's specific to new code in Geeqie 1.1 and crashes in libtiff. Geeqie 1.0 is not affected.

Re: [Geeqie-devel] Geeqie failed to open a g3 tiff fax file segmentation fault?
I've only had a brief look at Geeqie's image_load_tiff.c after compiling from scratch. Comments in the source indidicate that using libtiff is troublsome. Something in the way how libtiff is used may be the culprit. The following value is suspicous (-1): > rowsperstrip = 4294967295 > if( TIFFGetField(tiff, TIFFTAG_ROWSPERSTRIP, &rowsperstrip) ) If forcing this value to 1 instead of -1, the test image displays, but is mirrored vertically. -- Fedora release 18 (Spherical Cow) - Linux 3.6.10-4.fc18.x86_64 loadavg: 0.17 0.26 0.35 -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.

Haven't had time to dig further. The implementation might be incomplete, e.g. the "transform" value is set but not used elsewhere.
