Following problem:
I can upload a pdf file (450 kB) to the wiki or files section without any trouble.
After I downloaded the file, it's corrupted -> it can only partly be displayed in adobe.
Same happens to dwf (150 kB) or dwg (450 kB) files. The dwf file cannot be displayed at all and the dwg file is creating error messages in autocad during opening.
The file size is always the same like before.

If I do the same with a log file (2 MB) everything works fine.

Any ideas?

It looks like I have the same problem.
I'm using
Ubuntu 10.04 LTS Server Edition
redmine 0.9.3-1 with mysql

It looks strange, like the content get's mixed up after some buffer is used.

I've added 2 files.
Test.pdf - the file created by copy&paste of random content
and
Test_download.pdf - The same file after downloading it from a ticket.

and now the second file

Could you checksum the file before/after upload ?
The uploaded files go to /var/lib/redmine/

Shure:

local file:
md5sum -b /freigabe/tmp/Test.pdf
3256926035bad98fa8b53853ee05aa87 */freigabe/tmp/Test.pdf

Uploaded file (on server):
md5sum -b 100607195738_Test.pdf
641846ef9e348283ee438e4e43f60aff *100607195738_Test.pdf

Downloaded file (local):
md5sum -b /freigabe/tmp/Test_download.pdf
641846ef9e348283ee438e4e43f60aff */freigabe/tmp/Test_download.pdf

Oh, this looks interesting:

I've uplaoded the same file more than one time:

md5sum -b *Test*
641846ef9e348283ee438e4e43f60aff *100607195738_Test.pdf

looks for me, like there is something going wrong, but in the same reproducable way.

3256926035bad98fa8b53853ee05aa87 would be the correct one, but I didn't get this one since now.
