Bug Description

Binary package hint: python-qt4

python-qt4 causes the 'ebook-viewer' program (part of Calibre) to segfault. Calibre's bug tracker has closed the issue as "not our fault" at http://calibre.kovidgoyal.net/ticket/2224.

Steps to reproduce:
* Install calibre
* Run 'ebook-viewer' on a .mobi file
* Observe that it segfaults (If it doesn't, try again; It appears to be inconsistent, but usually crashes for me)

I have the same problem with calibre vs. 0.5.14 on Slackware. The main developer posted a comment on a forum to temporarily fix this issue. According to him you need to comment out this line:
self.view.setProperty("url", QtCore.QVariant(QtCore.QUrl("about:blank")))
in /usr/lib*/python*/site-packages/calibre/gui2/viewer/main_ui.py. This solution worked for me, so now I can read EPUB files in the ebook-viewer.

More of a QtWebKit crash than a PyQt one.

This appears to be the corresponding upstream report: http://www.qtsoftware.com/developer/task-tracker/index_html?method=entry&id=250187
(Both of these are crashes in WebCore::Frame::loader)
