Description Bernhard Rosenkraenzer 2004-05-05 02:27:47 UTC

Version:           3.2.2 (using KDE KDE 3.2.2)
Installed from:    Compiled From Sources
Compiler:          gcc 3.3.3 
OS:          Linux

SSIA - if a QProcess is running, opening the dialog from a KURLRequester takes forever.

If you remove the _p->start(); line from the test case I'm attaching, everything works as expected.
If you leave it in, the UI comes up, and when you open the file selector dialog via the KURLRequester, it hangs forever.

Tested on KDE 3.2.2 with Qt 3.3.2 (qt-copy from today's CVS)

Comment 2 Bernhard Rosenkraenzer 2004-05-05 03:04:16 UTC

I've just verified that replacing the QProcess with a KProcess is a workaround for the problem -- nevertheless it should probably be addressed, it may well be the root of other issues

Qt bug: Qt installs a signal handler for SIGCHLD and does not call any previously installed SIGCHLD handler.
