Save dialog crashes on Ubuntu 13.10

[knewter]

If I click the 'Save' button from the main interface, kidsruby crashes in Ubuntu 13.10.

[hunterboerner]

Is there some sort of log you could give us?

[knewter]

Oops, didn't even think to run it from the command line to get you a dump. No excuse, I know better than this.

Here you go.

[hunterboerner]

What version of KidsRuby are you running?

EDIT: Qt version too.

[hunterboerner]

@deadprogram may know what's going on.

[deadprogram]

The version of Ruby that KidsRuby currently supports is 1.9.2 p-290. This is due to the Qtbindings gem (https://github.com/ryanmelt/qtbindings) that up until some recent new maintainer activity did not support Ruby 2.0. I see some new commits in that repo, I will try to update to Ruby 2.0 and see what happens... in the meantime, can you try with 1.9.2-p290? I run Ubuntu 13.10 myself, and was not able to repro your issue.

[knewter]

I modified the kidsruby executable that was installed, changing the last line to:

...
#ruby /usr/local/kidsruby/main.rb
/home/jadams/.rvm/rubies/ruby-1.9.2-p290/bin/ruby /usr/local/kidsruby/main.rb

Then when I try to launch it I get a fun, different segfault:

This is obviously because qtruby4.so is a 32 bit lib, though I don't know why that is exactly. Perhaps there's an easier way to run it on that specific version - not really sure, I don't deal with 'installed' ruby packages basically ever.

[deadprogram]

I thought you were running from source. This sounds more like a package problem now... @adzankich created the debian installer.
