Hello Martintxo, I am just looking at crashes of some random packages and found your backtrace. Thats already a good start. As I it looks like you had installed the package amule-utils-gui-dbgsym maybe you could also install these packages:
libwxbase3.0-0v5-dbgsym libwxgtk3.0-0v5-dbgsym libgtk2.0-0-dbgsym libglib2.0-0-dbgsym That way the backtrace would contain line information not just for the main executable but also for the .so files. I guess it will point into wxWindow::DoClientToScreen [1] at the top frames. And yes, the duplicate lines are of no help, so ommiting most of them is good, like you did. And because it was not reproducible for me, you might add which desktop environment you are using, and maybe note if which theme is in use. Kind regards, Bernhard [1] https://sources.debian.org/src/wxwidgets3.0/3.0.4+dfsg-9/src/gtk/window.cpp/#L3158
