Hi there !
As we had problems with crashes when using the textfile and qlist objects I investigated what the causes could be and came up with a small patch against x_qlist.c.
This has been a few weeks ago, the same problems seem to occur with 0.28, therefore I'm posting the patch, which helped me to solve the problem.

(PS: if you are in the "src" directory, you have to apply with "patch -p2 < patch-0.28-qlist" )
