Details:

I first recieved a SIGSEGV when attempting to /join #hurp. Weechat immediately
crashed. Upon trying to restart weechat, I recieve the same problem.

Here is the backtrace.

Program received signal SIGSEGV, Segmentation fault.

>From this I believe that is a problem with the condition of one of my bars. I
had previously set new conditions only 30-60 minutes prior, and while they
worked at the time, they now appear to be causing severe problems.

I have some of the following conditions:
"${buffer.title} !~ ^[^#]+mon"
"${active} && ${buffer.title} !~ ^[^#]+mon"
"${inactive} && ${buffer.title} !~ ^[^#]+mon"
"${active}"
"${inactive}"

Additionally, I have attached the weechat_crash.log
