[Users] Can't check S/Mime signatures with Claws 3.11.1 on Ubuntu 14.02

[Jan Willamowius]

Hi,

for _all_ S/Mime signatures I get the error "The signature can't be
checked - Unsupported protocol". This also happens for signatures that
I was able to check with older versions of Claws running on SuSE 13.1.

Checking signatures on the command line with gpgsm works fine.

Here is the debug output:

smime.c:224:Checking S/MIME signature
sgpgme.c:406:data 0x7f0a1fffdbb8 (3081 3178)
sgpgme.c:73:op_verify err Unsupported protocol
summaryview.c:3650:TIMING summary_display_msg_full : 0s050ms
mimeview.c:1143:mimeview_check_sig_thread_cb
sgpgme.c:91:system error
sgpgme.c:91:system error

Could it be that the libgpgme version on Ubuntu is too old ? Its 1.4.3
while my old system had 1.4.4.

Any other ideas ?

Thanks,
Jan
