Bug Description

This behaviour can be exploited using amule 2.1.3-1ubuntu1 on an up-to-date Feisty.

Steps to reproduce the crash:
1) Open amule
2) Connect to any server you like
3) Enter a description in Name field and press Start button
4) Close the tab just opened as soon as possible
5) amule crashes. See attached logs for backtrace

This can be related to bug #59138 in wxwidgets2.6 (now solved), but it is slightly different. If you try to close a private message tab or a completed research tab, everything goes fine. it seems it only affects active tabs.

Followed same procedure done by Luca Falavigna.

amule crashes when closing the first search tab, before searching ends (when "start" button is still greyed out).
This behavior is not reproducible in other search tabs when one already present.

Unluckily amule depends strictly on wxwidgets2.6. I tried to recompile it with wxwidgets2.8 support but it failed.

This happens with 2.8 too in Gutsy.

I have a similar issue using aMule 2.2.2 on Ubuntu 8.10 Release Candidate.

aMule often crashes when I close the last opened tab in the Search page. I don't have this issue using aMule 2.2.2 on Arch Linux.

Is this still a problem with aMule 2.2.4?
