I forgot to mention that the 
file '/usr/share/squirrelmail/functions/decode/big5.php' on line 55 from 
package 'squirrelmail-decode' makes Apache to consume all memory available 
before PHP 30 second timeout is reached.

Confirmed, and the backtrace is:

(gdb) bt

Looks to me like it's probably a librecode bug?  Reassigning.

Hello.

I received the following report from the debian bug system, and, apparently,
it seems to be a bug in librecode.

Thanks.

Well, it seems it was not, after all.

I can't reproduce this on a lenny amd64 system, so I looked at php
changelog and noticed that this bug is *suspiciously* similar to
Bug#459020 in php, which was fixed in etch in version 5.2.0-8+etch11~p1.

So, reassigning again. I believe the bug may be closed, but I leave
that to the PHP maintainers.

Cc: to recode-bugs as well, where I mistakenly forwarded this.
François: you can forget about this one :-)

Thanks.
