App startup fails

[clobrano]

On Fedora 36, using wayland, launching Hamster from the Application list (or Dock, once pinned), does not work.

journalctl log shows this error

g_app_launch_context_launch_failed: assertion 'startup_notify_id != NULL' failed

Hamster installed via Flatpak, v3.0.2

It seemed different that #713, so I opened a new bug, feel free to close it if is the same problem.

I just notice that it crashes only on Gnome (in Fedora 36), while un KDE it works just fine.
Let me know if I can help with more info

EDIT: I will take this back. Today I got the same error on KDE too. Yesterday worked fine because I lunched it from Discover 🤷

I have the same issue on Fedora 37, using wayland and Gnome. When I try to start the hamster GUI nothing happens and I see the following in the logs:

I installed hamster from source using the master branch at 71076a5.

A simple way to reproduce the issue is by executing hamster (or hamster-service) directly on the CLI:

$ hamster        
Traceback (most recent call last):
  File "/usr/bin/hamster", line 415, in <module>
    i18n.setup_i18n()
  File "/usr/lib/python3.11/site-packages/hamster/lib/i18n.py", line 24, in setup_i18n
    module.bind_textdomain_codeset('hamster','utf8')
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'gettext' has no attribute 'bind_textdomain_codeset'

Even though I'm no Python expert, I suspect this to be a Python 3.11 issue. I found the following line in the Python 3.11 changelog:

Removed the deprecated gettext functions lgettext(), ldgettext(), lngettext() and ldngettext(). Also removed the bind_textdomain_codeset() function, the NullTranslations.output_charset() and NullTranslations.set_output_charset() methods, and the codeset parameter of translation() and install(), since they are only used for the l*gettext() functions. (Contributed by Dong-hee Na and Serhiy Storchaka in bpo-44235.)

When I remove the offending bind_textdomain_codeset function call and reinstall hamster it seems to work as expected 🎉 .

The above is surely necessary, however installing from source (master HEAD) does not incurr into this issue anyway
