QCoreApplication::notifyInternal Segmentation fault

Hello I'm developing a shared library in c++ and I'm testing it using a QT interface. Everything seemed ok, but suddenly the application crashed and give me the following core dump:

Program terminated with signal 11, Segmentation fault. 0 0x00401b26 in QCoreApplication::notifyInternal(QObject*, QEvent*) () from /usr/lib/libQtCore.so.4

I'm running in ubu开发者_如何转开发ntu 10.10 installed in a SD card, and I'm using QT 4.7.0. In Windows the application works ok, and in Linux too, until the application crashed at a random time. I don't know if a QT bug with ubuntu or something like that, because I have read in internet, applications with similar core dump.

Thanks!
