no jpgs via http - https works fine (apache 1.3.34 and 2.2.3)

[Philipp Flesch <philipp@phflesch.de>]

Hi!
We are running an HP RX2600 Itanium Server with debian eth (kernel 
2.6.18) for some local education projects.
Since we applied some updates (marked as non critical) via apt-get 
upgrade we have got problems with some jpgs.

Loading the images via https everything works fine. Loading the images 
via http we got into a loop without generating any error in the logs.
After resizing the picture with gimp the broken picture works fine.

We found out, that some broken pictures have got EXIF-headers with 
camera information. Most of the pictures were uploaded months ago and 
have already been displayed without any problems before the "patchday".

Please feel free to try out yourself:

apache 1.3.34
http://wvbg.bndlg.de/~max/apache vs. https://wvbg.bndlg.de/~max/apache

apache 2.2.3
http://wvbg.bndlg.de:81/~max/apache


Transfering the pictures to an apache running i386 debian and apache 
1.3.34 everything works fine, too.

Any hints?
