[dvillalobos]

Hi,

I got a sigsegv wherever I call setIcon, any idea?

@
exitAction->setIcon(QIcon::fromTheme("application-exit", QIcon(":/images/svg/server-database.svg")));

I'm not sure if you run it on Linux platform. Maybe you can use debug tool for tracing this error. like gdb. Usually, this kind of error is very simple if you use gdb

Maybe you call setIcon before initialise the action?
Anyway there is very few code, for saying something.

I found the problem. It is not in setIcon is in QIcon::fromTheme.

Does someone know if there is a problem with fromTheme?

The code works fine on Qt 4.8 same machine. Any Ideas?
