Apps printing a lot of text to stderr eventually freeze when run with gksu
Encountered in Ubuntu 13.04 and Mint 15.
Steps to reproduce:
1. gksu synaptic
2. Turn off "Settings -> Preferences -> General -> Show package properties in the main window" if it was on (or else you won't get a lot of warnings in stderr).
3. Click on package list and start browsing it with Up and Down keys. You may also use the mouse, but it will take more time.
The big load of messages thrown to stderr is described here: https:/
The freeze itself is reported here: https:/
1. Download the archive from the attachment and unpack it.
2. Install g++ and libgtkmm-3.0-dev
3. g++ main.cc helloworld.cc -o test `pkg-config gtkmm-3.0 --cflags --libs`
4. chmod +x test
5. gksu ./test
6. Start clicking on the button (or pressing Enter)
The source code was taken from gtkmm examples: https:/
With messages number set to 20 there's an interesting side effect: shortly before freeze, one of these messages gets actually printed to the console instead of being buffered until the app termination.
