It may be that libQtWebKit is habitually mishandling that error, or it may be that there's something else that's going on. If this were a program, not a shared library Run addr2line -e yourSegfaultingProgram 00007f9bebcca90d (and repeat for the other instruction pointer values given) to see where the error is happening. Better, get a debug-instrumented build, and reproduce the problem under a debugger such as gdb. Since it's a shared library You're hosed, unfortunately; it's not possible to know where the libraries were placed in memory by the dynamic linker after-the-fact. Reproduce the problem under gdb. What the error means Here's the breakdown of the fields: address (after the at) - the location in memory the code is trying to access (it's likely that 10 and 11 are offsets from a pointer we expect to be set to a valid value but which is instead pointing to 0) ip - instruction pointer, ie. where the code which is trying to do this lives sp - stack pointer error - An error code for page faults; see below for what this means on
