user session broken in some rare cases

[user2589]

To reproduce this issue:

• session backend is cached or cached_db,
• cache backend is memcached
• po file is 700kb or more

as lang_sel view stores po file in session, and memcached doesn't store values bigger than 1Mb, session is cut and some data may be lost

Yes, I reckon this could happen. I wouldn't recommend having a 700k pofile in the first place, but this could indeed happen.
Any suggestions on how to handle this?

I'll make a pull request for fix soon
