[otrs] Attachments are broken after downloads

Hi,

It did not let me sleep. I investigated the process.
I put a little hack into the ArticleStorageDB.pm which provides me the 
size of the attachment read.
It was correct. The second turn I put the whole encoded content into a 
temp file.
It's size also looked me good. Then I run
perl -w -MMIME::Base64 -ne 'print decode_base64($_)' <oo.txt >oo.pdf
The result is then the decode process cut the output at 3 Mb however 
it's 3.5 Mb.
It happened at the same size  3104874. It's a kind of magic number. I 
did not find any restrictions related to MIME::Base64.
Of course I double checked the filesystem allocation as well.
For a different approach I encoded a tgz (quite big, around 35 Mb) then 
decoded it again
It was perfect.
So I suspect there is "something" in the stored content which drives 
decode_base64 onto wrong way.
