[Pulp-list] Mongodb crashes using regex filter

Hi,

Using "--match" when searching the contents of a repository crashes mongodb.

In mongodb.log, the following line can be seen:
/usr/bin/mongod: symbol lookup error: /usr/bin/mongod: undefined symbol: 
_ZN7pcrecpp2RE4InitEPKcPKNS_10RE_OptionsE

When calling "service mongod stop ; service mongod start" it works again.

Googling the error, I found some links telling me - at least for Ubuntu 
- , that it is connected to libpcre - which is installed on my RHEL 
Machine....

The command used, was this one:

#> pulp-admin rpm repo content rpm --repo-id=se2ve-test  --match 
"name=ssh.*"
An internal error occurred on the Pulp server. More information can be 
found in the client log file ~/.pulp/admin.log.

Environment:
* RHEL 6.3, x86_64
* mongodb-2.2.3-4.el6.x86_64 from epel
* pulp-server-2.1.3-1.el6.noarch

best regards,
florian
