Somehow your core file doesn't quite work for me. At least it doesn' tell me that it failed in strlen(). Therefor I'm asking you for the output of bt full from within gdb after the coredump occured. TIA, Flo

ok.. this seems to indicate that gpgme_data_release_and_get_mem returns a NULL pointer. Please tell gdb to set a breakpoint at perl_gpgme_data_to_sv and tell me what the values of buf and len are before and after the call to gpgme_data_release_and_get_mem. -Flo

I just tested the latest release (0.02) against your version of libgpgme (1.1.4). The test suite as well as the snippet that is causing your problem worked fine. What version of gpgme are you using? Except for that I don't have an idea what might be wrong unless you can provide some more debugging information. -Flo

Does http://files.perldition.org/crypt_gpgme_coredump_fix.diff fix your issue as well?

I'm quite certain that this issue has been fixed with version 0.03 although the reporter didn't confirm it. Feel free to reopen if the bug still applies.
