I'm not familiar with UserLAnd but I will try a few questions :
Do you install  ratpoison  from the Debian repositories or do you compile
from source ? I don't know if compiling from source is possible on UserLAnd ,
I'm just asking.

I find this confusing. Which C library ? Where do you see the message
about segmentation fault ? Is there anything related in  /var/log/messages ?
What about if you do   dmesg | tail   ? What do you mean "Window manager works" 
Assuming you mean  ratpoison  , do you mean that it works until you get
segmentation fault or that somehow you a get a segmentation fault message
and yet  ratpoison  continues to work ? What exactly were you doing right
before getting the message ?

A segmentation fault generally means that some programme tried to access
memory it wasn't supposed to. In a robust system this may terminate the
programme responsible but should have no effect on the rest of the system.
Whether UserLAnd is robust enough I don't know but if a segmentation fault of
ratpoison  or anything else causes UserLAnd to become unstable then that's a
bug in UserLAnd and should be reported to its maintainers. So I would say you
should continue to run  ratpoison  and see if any crash of  ratpoison
(assuming this is what happens , you're not clear enough) affects the rest of
the system. If it does , you should report it to the UserLAnd maintainers. In
the meantime try to answer my other questions above.
