[EP-tech] Segfault when trying to download pdf file

[Štefan Sakalík]

Hello,
I have installed eprints 3.3.10 from 'http://deb.eprints.org/ stable' on
ubuntu 10.04 (x64). Eprints works fine but when I try to download
a pdf file that was published, apache gives me segfault, and core
backtrace doesn't tell me much:

Do you know what could be the problem? Google search gave me this page:
http://www.eprints.org/files/eprints2/eprints-2.2/docs/html/troubleshooting.html#apache%20crashes%20with%20a%20segmentation%20fault
which suggests compiling apache from source without expat but I really
don't want to do that.
