-- Information about the crash:
- What I was doing when the application crashed:
I am having problems with the printers on my computer, where it crashes when
trying to do something related with them.
e.g.:
* libreoffice crashes on startup, I have to disable cups previously every time
* when trying to open the "Print" dialog on Okular, I also get a crash.
* `lpstat -p -d` crashes with the following error:
"dbus[794440]: arguments to dbus_message_iter_append_basic() were incorrect,
assertion "_dbus_check_is_valid_utf8 (*string_p)" failed in file
../../../dbus/dbus-message.c line 2760.
This is normally a bug in some application using the D-Bus library.
D-Bus not built with -rdynamic so unable to print a backtrace
[1]794440 IOT instruction (core dumped) lpstat -p -d"
This is the same type of crash info that I get from okular and libreoffice.
The crash can be reproduced every time.
