Details:

So far Weechat has crashed several times while scrolling in /iset using the
mouse wheel (that looks like what triggers the bug, although I'm not 100%
sure).

This time it actually crashed twice -- once while scrolling, then while
printing the debug dump. Backtrace below.

Version: WeeChat 0.4.2-dev (git: v0.4.1-2-g2e43bac)
