The problem seems less likely to be in Inkscape's codebase itself - something else on your system appears to trigger the crash, likely when it tries to open the PDF import settings dialog (EPS files are converted to PDF on-the-fly with ps2pdf, and then imported as PDF files using internal routines, and with the PDF-based AI files AFAIU the proprietary parts are stripped and the remaining content is opened as PDF).

Hmm, I'd have hoped for somewhat more verbose output :(
Any chance you could run inkscape from gdb, and create a backtrace when the crash occurs?
