Hi there,
I'm running Kile 2.1 on Linux Mint 16 (based on Ubuntu 13), and since upgrading from 2.0 I've encountered a weird bug, whereby everything works just fine if I have a document that doesn't use bibtex or have a bibliography in it, but, for whatever reason, segfaults if I do. This happens every single time I click the 'QuickBuild' button, and is rather irritating. I'm sure my latex configuration and documents are all fine -- they were working before I upgraded recently. Minimal working examples -- with nothing more than a document class and a bibliography -- crash. Going to Konsole and typing in pdflatex *.tex; bibtex *.aux; pdflatex *.tex -- works fine.
Please advise!
KDE's crash reporting system won't let me report the crash as it cannot find appropriate debugging symbols to install. Here's the unhelpful backtrace:



Reproducible: Always

Steps to Reproduce:
1. On my system, which is, I believe, vanilla, create a test file in /tmp containing the following 
\documentclass{article}

\begin{document}
 Hello, world!\cite{Tyler2009}
 \bibliographystyle{ieeetr}
 \bibliography{Bibliography.bib}
\end{document}
2. Press 'Quick build'
3. Segfault (whether or not Bibliography.bib exists).
Actual Results:  
Segfault

Expected Results:  
Compile everything cleanly 

Application: Kile (kile), signal: Segmentation fault
