Description of problem: trying to save an edited image as jpeg eats up all memory, and after the crash of /usr/lib64/gimp/2.0/plug-ins/file-jpeg the error is 1) Bogus marker length 2) /usr/lib64/gimp/2.0/plug-ins/file-jpeg: fatal error: (segmentation fault) saving as png does work, though, but it does have much less exif information in it Version-Release number of selected component (if applicable): gimp-help-2.4.2-5.fc12.noarch gimp-2.6.8-1.fc12.x86_64 gimp-help-browser-2.6.8-1.fc12.x86_64 gimp-data-extras-2.0.2-3.fc12.noarch gimp-debuginfo-2.6.8-1.fc13.x86_64 gimp-libs-2.6.8-1.fc12.x86_64 ufraw-common-0.16-1.fc12.x86_64 ufraw-0.16-1.fc12.x86_64 ufraw-gimp-0.16-1.fc12.x86_64 How reproducible: I put the two images where it's happening so far at http://lklaus.homelinux.org/image1.orf and image2.orf resp. (large!) Steps to Reproduce: 1. open image 2. save as jpg Actual results: save as jpeg should be fine Expected results: Additional info: You need ufraw for the raw image
Created attachment 412791 [details] test image How to play easier: 1. open the file one_black_pixel.xcf (of attachment). 2. save the image as one_black_pixel.JPG. 3. processor is busy for about 1 minute. 4. on-screen message: GIMP Message Saving '/home/bond/HOSTING/bug/one_black_pixel.JPG' failed: JPEG image plug-in could not save image 5. console message: Bogus marker length This does not happen with all images, and approximately one out of 100. P.S. conversion to JPG works correctly in Arch Linux
(In reply to comment #1) Thanks for the easy reproducer. > P.S. > conversion to JPG works correctly in Arch Linux Which version of gimp is this?
Never mind the Arch Linux gimp version... I strongly suspect Arch has a more up to date version of libexif than Fedora (which has 0.6.16 instead of .19 which is current). This is why I suspect libexif to be the culprit: In order to not have to wait for the crash too long (and clog the machine), I limited the size of virtual memory available to GIMP to 1GB: nils@gibraltar:~> ulimit -v $((1024*1024)) Then I started gimp, opening your reproducer image and attempting to save it as a JPEG: nils@gibraltar:~> gimp --stack-trace-mode=always Download/one_black_pixel.xcf /usr/lib64/gimp/2.0/plug-ins/file-jpeg: fatal error: Segmentation fault #0 0x0000003b0560ec4e in waitpid () from /lib64/libpthread.so.0 #1 0x0000003b07a159d2 in g_on_error_stack_trace () #2 0x0000003b0d212a20 in ??

On http://libexif.cvs.sourceforge.net/viewvc/libexif/libexif/NEWS?view=markup&pathrev=libexif-0_6_19-release the release notes of libexif-0.6.19 have the following: libexif-0.6.19 (2009-11-12): [...] * Fixed a heap buffer overflow during tag format conversion Changing component to libexif.

Maybe I'm hitting another bug, but I'm suddenly unable to save to jpeg without getting a segfault in /usr/lib64/gimp/2.0/plug-ins/file-jpeg; Fedora 12 with gimp-2.6.8-1.fc12.x86_64. Updating from libexif-0.6.16-4.fc12.x86_64 to libexif-0.6.19-1.fc12.x86_64 has no effect. However, my symptoms are slightly different: it says nothing about "Bogus marker length", and takes nothing special to trigger -- any attempt to save any image as a jpeg, regardless of origin, fails.
libexif-0.6.19-1.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report.
