[ruby-fltk-users] ruby fltk crash in file browser

[<sz...@t-...>]

I downloaded today the latest sources of fltk and ruby-fltk.

I am using Suse Linux 7.3 (Kernel 2.4.10), ruby-fltk-0.4, fltk-1.1.0b6 and
configured the ruby fltk with the option --disable-gl (otherwise there were
unresolved symbols in the fltk so).

I tried some of your examples, and if I click around a while in the
file browser, then it crashes with the following trace:
(gdb) r file_chooser.rb
Starting program: /usr/local/bin/ruby file_chooser.rb

Program received signal SIGSEGV, Segmentation fault.
