expat / gimp problem
A few days ago, I updated my patch to fix the current expat vulnerabilities, tested that my normal desktop seemed to work, and committed it (part of the preparations for ghostscript-9.00). Along the way, I noticed that my previous patch had fallen out of my script. Since then I've made several other upgrades to my desktops (particularly freetype, but also xorg-server and the ati driver, to see if my xorg sometimes crashes on radeon r100/r200 problem still exists - so far, it's too early to say). Then I took a break from gs9 to catch up with editing my photos. I'm using the gimp, and my pics need a *lot* of adjustment, partly because my poor balance and taking most one-handed means my idea of which way is up is only approximate. So, lots of use for the 'rotate' and 'perspective' tools. Unfortunately, the perspective tool had become all-but unusable (either the preview didn't show what changed, or else I couldn't get the controls on the corner of the image to move). After a lot of experimentation, and getting ready to revert everything I had changed, I've now got the control working adequately. The problem is the expat patch. Unfortunately, that patch ought to be used, because it fixes known vulnerabilities. For now, this is just a heads-up that it seems to break the perspective control in the gimp. It's taken me 3 days to pin the blame here, I'm still not entirely convinced (for one thing, rendering of the gimp windows was horribly slow, and now that I've reverted this patch it still seems slow). Comments welcome. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

Comments welcome. Unfortunately, while you've given lots of detailed information, there still isn't much to point a finger at. A couple of stabs in the dark is all that I have to offer. It's been a while since I've used Gimp, so I don't know what is in in ~/.gimp, but did you move it out of the way and start fresh? Would seem logical (at least to me) that some items in there would use xml and you messed with expat. First instinct and all...sounds plausible at least. Also, are the slowdowns in any way similar to the slow resize issues you had before with xorg-server-1.9.X? -- DJ Lucas -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
