Hi Mattia,

I've seen RT#41716 - and this RT is more or less the same report with
another background.

We (pkgsrc) package some perl modules using Wx - at least Padre and some
plugins. All these package fail the bulk builds with perl core dumps,
because of the Wx requirement.

I used the severity "Critical", because this bug prevents creating of
binary packages for those modules.

A backtrace of the dump is included.

You can reproduce it simply by doing "env DISPLAY= prove t".

Best regards,
Jens
