RE: [Fxruby-users] Error: FXRbGetRubyObj(this=0x084e7fb8) returns non-Qnil

[Daniel S. <da...@pr...>]

It looks to me like calling any of the connect() methods on a treelist
is prone to error (my code was with SEL_DELETED and SEL_INSERTED on a
treelist)

I've edited your tycho.rb file by deleting a bunch of code. I've added
code into two places (marked with -- daniels).

It appears that the pim.main.tree.connect(SEL_COMMAND) is the root
problem. Comment out that section and it exits cleanly.
