Dear Maintainer,

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

Thank you for your consideration,
Santiago

Hi,

(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!

Dear Maintainer,

One addition to the previous report : restarting transmission-gtk restarts the
transfers in progress.

HTH,

  Hi,

  I also have been hit by this bug when trying to get the DVD1 of trixie.
tranmission-gtk crashes (without any interaction from my part) with the same error message in the terminal (when run from the terminal).
Partial download of the DVD (1 to 3 Go) is lost after each crash (the transfert restart from the begining)
but the torrent is still there (no need to re-add it).

  Looking at the bug report, I saw the initial reporter was with a French local, as myself.
I restarted transmission-gtk with LC_ALL=C, and I've been able to complete the whole transfert (4Go) without any problem.

  Restarting in French local (without LC_ALL=C) with data present does not lead to any crash.
  Restarting in French local (without LC_ALL=C) after removing the DVD leads to a crash again.
It seams to me that the crash occurs when the countdown switch from 1 minute to seconds...

In this latter case, the download finished after the crash of the interface and restarting transmission-gtk shows me a complete transfert.
However, the previous (with LC_ALL=C) download and the latter one have different contents (different sha256sum, the first being good according to the Debian website)
After a few minutes (typing this bug report...), transmission-gtk shows me:
"Erreur locale : « Please Verify Local Data! Piece #988 is corrupt. »
I clicked on "Vérifier les données locales" and the transfert restarted.
Then it crashes again. And it seams it was when the reminding time was less than 1 min again.

A new launch of transmission-gtk restarted the transfert, with same thing (crash when < 1 min left).

Restarting with LC_ALL=C completed the transfert. And after "1 minute left", I've been able to see "X secondes left"

  Regards,
    Vincent

Hi,

Thanks a lot! I found something wrong. The following patch should fix this,
will report back later when I get the chance to test, and if ok, will
prepare an updated version.
