[Qt-interest] help with tslib

[Chris Burke]

Hi Fabio,

I've recently had problems with tslib builds but I never saw the 
"ts_calibrated" error, only segfaults. I would suggest going into your 
filesys and removing ALL files having to do with tslib, recompiling, and 
reinstalling to the filesys. Some of our issues had to do with having 
tslib compiled for a different filesys.

If your ts_print is segfaulting right away, it sounds like the same type 
of issue.
