Looks like a bug in python2-pyqt5:

from PyQt5.QtWidgets import QApplication
from PyQt5.QtGui import QFontMetrics
app = QApplication([])
QFontMetrics(app.font()).inFont(u'\u2605')

Traceback (most recent call last):
  File "292.py", line 4, in <module>
    QFontMetrics(app.font()).inFont(u'\u2605')

Update of python2-pyqt5 from 5.12.3-2 to 5.13.0-1 seems to have caused TortoiseHg to throw an error. I've found downgrading it back to 5.12.3-2 lets it keep working for now.

sotoleni, it looks like this is a problem with PyQt5 on Python 2, therefore it affects for example tortoisehg and Calibre, which both use Python 2.

$ python2 -c 'import PyQt5.QtCore'
Fatal Python error: PyQt5.QtCore: Unable to embed qt.conf
Aborted (core dumped)

Here is the bug report against the python2-pyqt5 package:

https://bugs.archlinux.org/task/63051

Edit: has been fixed in python2-pyqt5 5.2.3-2

After the latest update of Qt5 packages of the Archlinux I get this startup error: Fatal Python error: PyQt5.QtCore: Unable to embed qt.conf bash: “thg” terminated by signal SIGABRT (Abort)

I tried to "makepkg" another time and I get:

running install running build running build_config creating build creating build/lib creating build/lib/tortoisehg creating build/lib/tortoisehg/util generating build/lib/tortoisehg/util/config.py from setup.py Fatal Python error: PyQt5.QtCore: Unable to embed qt.conf /home/toni/.cache/pacaur/tortoisehg/PKGBUILD: line 26: 32336 Aborted (core dumped) python2 setup.py install --prefix=/usr --root="${pkgdir}" ==> ERROR: A failure occurred in package(). Aborting...

Has anybody a solution? Thank you!

The latest build of TortoiseHg is 4.9.1, which does not support 5. However, if you get the latest source (which may have bugs) and set it up directly, it will work.

You can clone the latest by running (hg clone https://bitbucket.org/tortoisehg/thg)

TortoiseHg already accepts mercurial 5.0.

https://bitbucket.org/tortoisehg/thg/src/0b4bd9ebb4900b3db240879d04693c06a9ecc7ec/tortoisehg/util/hgversion.py?at=default

PKGBUILD: depends=('python2' 'mercurial>=4.8' 'mercurial<4.10'...

Yes, because thg checks that version.
