i totally agree on that. But i could only produce the bug with openarena.

i see two versions now : wheezy and sid.
Both have the problem.

Yes it did but at some point it became difficult to test.

I have prepared these logs :
- flares off on ioquake3 1.36+svn2287
  http://paste.debian.net/10242/
- flares on on ioquake3 1.36+svn2287
  http://paste.debian.net/10243/
- flares on on ioquake3  1.36+u20130504+g42eeb75-2
  http://paste.debian.net/10244/

a quick diff showed :

  ...loaded 1409 faces, 44 meshes, 0 trisurfs, 28 flares
  WARNING: reused image textures/flares/flarey.tga with mixed glWrapClampMode parm
  WARNING: reused image textures/flares/lava.tga with mixed glWrapClampMode parm

but i'm really not sure it means something.
