Arch Linux

I got the same error yesterday with eric5. I was using eric5 normally, but then it suddenly crashed. Since then this errors happens whenever I try to start eric5. Sent a bug report to the below email address but haven't gotten a reply yet.

An unhandled exception occurred. Please report the problem
using the error reporting dialog or via email to <eric5-bugs@eric-ide.python-projects.org>.

Considering the timing of these bug reports I checked the time stamps of my pacman updates and have found that an update of the following packages exactly coincided with the timing of the initial crash I experienced.

drwxr-xr-x 2 root root 4096 Jan 28 14:51 python2-qt-4.8.3-1
drwxr-xr-x 2 root root 4096 Jan 28 14:51 python2-sip-4.12.1-1

drwxr-xr-x 2 root root 4096 Jan 28 14:51 python-qt-4.8.3-1
drwxr-xr-x 2 root root 4096 Jan 28 14:51 python-sip-4.12.1-1

I'm therefore now 95% sure this bug is python(2)-qt and/or python(2)-sip related.

Triple posting. This may have something to do with it: http://www.riverbankcomputing.co.uk/news/pyqt-483

"
PyQt v4.8.3 has been released. This includes enhanced support for working with QVariant objects and Python v3.

* Added the QPyNullVariant class to the QVariant v2 API to allow null QVariants to be implemented.
* Added the optional type keyword argument to QSettings.value() to allow the type of the returned value to be specified.
* QDeclarativeItem will now act as a transparent proxy from any QML signals and JavaScript functions.
* Any QObject invokable methods can now be called transparently even if they haven't been explicitly wrapped.
* QWizardPage.registerField() can now take an unbound or bound signal as its changedSignal argument.
* Converted the Reference Guide to Sphinx.

That second bullet point?

Detlev Offenbach (eric's developper) pointed out the solution on eric's mailing list :
"""
These kind of issues usually arise from forgetting to rebuild QScintilla
Python bindings after a PyQt upgrade.
"""
This problem can be fixed by rebuilding the python(2)-qscintilla package.
At least it worked for me.

please try with python-qscintilla 2.4.6-6 and python2-qscintilla 2.4.6-5 (uploaded now)

python2-qscintilla 2.4.6-5 fixes the problem for me. Thank you.
