Hi,
With github pull request 151 I’ve made the stock browser sample gtk3
ready. If I scroll up and down in den list view, the program crashes
with a segfault. It seems to be in the ruby bindings. The original C
version doesn’t show this behavior.
$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
Here is the back trace:
Program received signal SIGSEGV, Segmentation fault.
