Hi,

Upon using transmission, it will sometimes crash when right-clicking on a torrent on the
list.
I haven't managed to trigger this bug reliably, but it certainly happens on a daily basis.

It seems to be due to a improper handling of string translations, but this is only my
guess.

Further context:
- Main interface language is French.
- I'm using gnome-shell.

Upon crashing, the following error message is shown on the terminal:

/usr/include/fmt/format-inl.h:40: assertion failed: argument not foundterminate called without an active exception

(still handling a hard drive crash on my GUI machine, so cannot investigate yet)

Can you provide a backtrace? Maybe running transmission in gdb?

$ sudo apt install gdb transmission-gtk-dbgsym
$ gdb transmission-gtk

Thanks!
