[Pkg-kde-extras] Bug#571721: [libstreamanalyzer0] Crashes all the time when scanning mails

[Peter Fritzsche]

Package: libstreamanalyzer0
Version: 0.7.1-1
Severity: important

I noticed that nepomuk cannot index my files and so i started
to investigate a little bit. I used

gdb --args /usr/bin/nepomukservicestub nepomukstrigiservice
r

To get a backtrace:

So it seems that the reason is MailEndAnalyzer or something like this
in libstreamanalyzer0. Is there a way to get the currently scanned file
when such a crash happened? I don't think I can make a personal mail
public for everyone, but maybe can give hints what is the reason for the
crash.
