Segmentation fault errors are also the one most hard to troubleshoot with a third party software.
If not the only way, it is most commonly to use a system debugger program for identifying what cause such kind of software crashes. The most useful tools are gdb (GNU debugger) and strace.
No matter that these utilities will show you information which library causes the unauthorized memory access further steps for fixing such error most of the time requires that you contact the vendor of the application directly. Of course if it comes to open source software it is highly recommended to check the mailing lists first.
