Python: 2.3.3 Qt: 3.2.2 PyQt: 3.8.1 QScintilla: 1.2 Eric snapshot-20040522 Bicycle Repair Man: 0.9
What was happening is that in Eric, specifically ViewManager.py, there is a python dictionary that was mapping extensions to its corresponding file dialog filter. This cache is being built in the method initFileFilters. The keys for the cache are python string objects which are the extensions, the data cached were QString Objects that were gotten from a QString list, so for example:
filtersList = QStringList.split(';;', someUTF8QString)
for filter in filtersList:
cache[key] = filterLater on what I found was happening was when trying to access data from that cache, i.e. pull out the QString, in Qt some sort of QString copy was occuring, trying to bump up the ref and that was crashing as the QString retrieved from the cache was either destroryed or it's C++ ref data was NULL, causing a crash inside of Qt. My fix was to instead of caching QString objects, to instead cache the objects as python unicode objects and things seemed to work fine.
so my loop above would look more like:
for filter in filtersList:
cache[key] = unicode(filter)I did not dig deep into pyqt or qt to see what was going on with the QString objects that was causing the referenceing to get messed up, but I found changing eric to above got around the problem.

First, thanks to Detlev Offenbach for a such a wonderful IDE! :^)
I checked it out last year, but could not use it since it did not yet support Quixote's PTLs in the Project Browser. I've been now using it daily for a few months.
This report refers to the following versions (drats, can't copy and paste from Help | Show Versions):
Eric: snapshot-20040529 Python: 2.3.4 Qt: 3.2.1 PyQt: 3.8 QScintilla: 1.2 Bycicle Repair Man: 0.9
running on Debian unstable, where I am avoiding upgrading PyQt to 3.10 on account of possible problems with Eric3.
1) Trying to open a file, either pressing Ctrl-O or selecting File | Open... crashes Eric3 immediately. Running it from the console, it just says "Segmentation fault".
