[Gambas-user] Segfault when the number of visible tabs in a Tabstrip goes to zero

[Bruce]

The form has a variable number of tabs. Their visibility is controlled 
by a user action on some "filter" buttons. When, as a result of the 
user's filtering clicks,  all the tabs .Visible are false the project 
segfaults.
The only info I get is "ASSERT failure in QList<T>::at: "index out of 
range", file /usr/include/QtCore/qlist.h, line 469"

I've tried both stepping through the project (which us very big), trying 
to get a backtrace at the failure and even researching how the IDE works 
when all the tabs are closed (no help, its a MDI form).

I've tried creating a small demo but it doesn't crash.

Next steps?
