emerge --info

dev-python/PyQt4-4.12.1
and dev-python/PyQt5-5.9.2
are installed here.

calibre writes to stdout after startup:

Traceback (most recent call last):
  File "/usr/lib64/calibre/calibre/gui2/store/loader.py", line 91, in load_cache
    obj, ver = self.load_object(src, key)

Maybe this shows something:

grep -r PyQt4 ~/.config/calibre
Comment 2 Jonas Stein gentoo-dev 2018-01-08 22:30:50 UTC
Thank you. grep -r PyQt4 ~/.config/calibre returns a hit

"kobo": "# -*-\n\nfrom __future__ import (unicode_literals, division, absolute_import, print_function)\nstore_version = 2 # Needed for dynamic plugin loading\n\n__license__ = 'GPL 3'\n__copyright__ = '2011, John Schember <john@nachtimwald.com>'\n__docformat__ = 'restructuredtext en'\n\nimport random\nimport urllib\nimport urllib2\nfrom contextlib import closing\n\nfrom lxml import html\n\nfrom PyQt4.Qt import QUrl\n\nfrom calibre import browser,

I think now that the message I saw was not two bugs, but one. So I will close the other ticket as duplicate and paste the complete output here.

My plugin settins say that no plugin is activated.
Perhaps an upstream bug that they try to load an obsolete plugin even if it is disabled?

Comment 4 Zac Medico gentoo-dev 2018-01-09 06:59:09 UTC
Since upstream doesn't support install from source, you might try to reproduce the issue using an "isolated" install in ~/calibre-bin, as described near the end of the binary install section here:
