After updating my machine to openSUSE 12.1 IMP users didn't get the  
content of e-mails displayed anymore.

The Horde log shows the error »PHP ERROR: preg_replace_callback():  
Compilation failed: POSIX collating elements are not supported at  
offset 225«

I'm running Horde_Text_Filter-1.1.1 and imp-5.0.15.

The cause are two occurrences of »[.]« the regex defined in  
ininitializeRegex() in  Linkurls.php. The term »[.« gets interpreted  
as the start of a POSIX collating (multi-character sequence).  
Apparently the PCRE parser does not check if a collate actually occurs  
within a bracket expression first. Thus, the period either needs to  
get escaped with a backslash or (better) the whole one-element bracket  
expression replaced with just »\.«

Please excuse me if this is a known issue, I haven't seen it discussed  
it in the bugtracker or fixed in Git so far.
