Known Issues

Application segfaults on close

Symptom: The application (sometimes) segfaults when closing, but after outputting MainWindow.closeEvent() and successfully saving the configuration. The version of PyQt is 4.7.2 or older.

Solution: Update PyQt (python-qt4-dev) to 4.7.3 or newer. For Ubuntu it is sufficient to update to 4.7.2-0ubuntu1.1 as the specific fix has been backported (Bug #561303).

XTerm looses characters on resize

Symptom: When using the rqt_shell plugin in the XTerm mode (default), resizing the plugin window cuts off already printed characters on the right of long lines. These don't reappear, when resizing to a larger window. This is a bug in XTerm itself and cannot be fixed in the rqt_shell plugin: https://bbs.archlinux.org/viewtopic.php?id=146023

Solution: Hope for an upstream fix or try one of the simpler non-interactive shell modes (settings button on the top right of the plugin dock widget). Patches to use another terminal emulator (maybe a native Python one) are welcome.

Rqt_bag does not publish all messages in my bag file

Symptom: When playing bag files in rqt_bag some messages are not published.

Solution: This is due to an optimization for dense bag files. rqt_bag only publishes messages "close" to the playhead and therefore can drop some messages even at slow speeds. If you wish to ensure publication of every message, right click the timeline and enable the "Play all messages" option.
