This could happen when a new file is created in the project tree with the
same name as the existing file and then the application loses focus.

This cancels editing of the filename (END_LABEL_EDIT), which shows a dialog
to confirm overwriting of the existing file. When the dialog is shown,
another event that cancels editing is generated (but in wxwidgets 2.9.5?),
which causes two dialogs to be displayed, which leads to a crash after the
second one is closed.

The workaround moves the overwrite confirmation to the IDLE event.

This appears to be a wxwidgets (2.9.5) issue and can be reproduced
by doing the following:

- Start editing a new item in the file tree;
- Right click on the text control (while editing);
- This opens a context menu and triggers ACTIVATE_APP event;
- `collectgarbage` call from that event causes a crash.

Switching garbage collection to ACTIVATE_APP event when the app becomes
active eliminates the crash.

This can be used to provide a filename that would then load proper spec
for the file (to take known API descriptions into account).
