size
Product: Breeze

Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal

SUMMARY
I get a segfault on long canvas sizes. Interestingly the fault is not only
depending on the canvas size but also on its content. Here a working example
and the one with the bug:
// Bug (seg. fault)
QMessageBox::question(qApp->activeWindow(),
QObject::tr("Saving"),
QObject::tr("Remember that when you move or rename image
files on your disk or the storage device become unavailable"));
// No Bug (just '\n' added)
QMessageBox::question(qApp->activeWindow(),
QObject::tr("Saving"),
QObject::tr("Remember that when you move or rename image
files\n on your disk or the storage device become unavailable"));
