I have replied to this twit with my "pay me for support or I'll forward your email to the list" form reply, but have also fixed the segfault in question. This is a segfault; it's not a security problem because a NULL pointer dereference can only be exploited in the kernel, not in userland (where the kernel promptly terminates the process). The fix can be downloaded here:
I wonder what idiotic excuse freetards will use to email me asking me for support next. Having the "I'll make your email public if you reply" note at least stops them from replying to my "pay me for support or take it to the list" form reply with some idiotic "But I'm entitled to free support!" reply.
And, yes, I have no problem with people sending me these kinds of reports to the mailing list.
