Bug#402402: lightspeed: crushes on start
Hi The reason that I reassigned it to that package is that I can not see how lightspeed can distroy the internal data structure in fontconfig so that it on finalize of the structure makes an assert. The lightspeed application do not even call this function. I think it is valid to forward this bug. But maybe I did not give enough proof on that the problem is in fontconfig. I can see a number of reasons why this has been introduced (changelog in reverse order): fontconfig (2.4.0-1) experimental; urgency=low * fontconfig update to 2.4.0 * binary shared mmap'd caches * split configuration -- Keith Packard [EMAIL PROTECTED] Sat, 9 Sep 2006 23:03:30 -0700 fontconfig (2.4.0-4) unstable; urgency=low * Clean up old fontcaches before creating new ones === * Config files moved to -config package in 2.3.2-2 -- Keith Packard [EMAIL PROTECTED] Wed, 13 Sep 2006 00:11:37 -0700 fontconfig (2.4.2-1) unstable; urgency=low * Incorporate old Galacian translation (closes 361259) * Add fc-list to fontconfig-udeb.

In lightspeed case the FcFinit is not called directly but rather via gtk libraries. I'm reassigning back to fontconfig. If the function that is calling fontconfig should be changed, please reassign to that library.

Bug#387606: Bug#402402: lightspeed: crushes on start
unmerge 387606 402402 reassign 387606 lightspeed severity 402402 important thanks Hi Doh!!! I have been looking in the wrong source tree for lightspeed. Sorry about that. I must have downloaded the sarge version some time ago and did not check which version I was looking into. Thanks a lot for that pointer. Detaching one of the bugs and reassign that back to lightspeed. I keep one of them on fontconfig however as the real bug is there still but not that serious as it is possible to go around it. I have made a recheck of the source that do this kind of things and I have not found any obvious faults. I checked for places where it could pass a null pointer to fontconfig but all such cases is handled. What I have done now is to comment out that FcFini call to make sure that lightspeed do not crash. It is not a good solution, but good enough to solve the immediate problem. Thanks a lot! New version uploaded to the archives.
