There is also no bugreport in python-qt3 indicating that someone else has this problem.

FWIW several users have reported crashes in minirok, so it may as well
be the same issue.

Good to know that rng is not the only one with this problem. I've written a bugreport against python-qt3 (#490340). There is also a small python script which helps to reproduce this bug. I think it has something to do with changing the text of the textbrowser when html is involved:

  python crash.py "foo"

will lead very seldom to segfaults, while

  python crash.py "<b>foo</b>"

will almost every second time lead to a segfault.


from qt import *
import sys
import threading

class Form(QMainWindow):
    def __init__(self,parent = None,name = None,fl = 0):
        self.browser = QTextBrowser(self, "browser")

if __name__ == '__main__':
    if len(sys.argv) < 2:
        print 'Usage: %s "some text"' % sys.argv[0]
    s = str(sys.argv[1])

    # setup qt stuff with a browser
    app = QApplication(sys.argv)
    app.connect(app, SIGNAL("lastWindowClosed()"), app, SLOT("quit()"))
    form = Form()

    # start a different thread and try to set the text in the browser
    # we wait 1.0 second -- just to make sure the change happens after the
    # start of app.exec_loop() below
    t = threading.Timer(1.0, form.browser.setText, (s, ))
