Hi,

I'm getting a crash that seems to be related to the K12 UAT file.

I get the following crash only when I try to load in a K12 capture file.

(lt-wireshark:25562): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()
14:54:17          Err  Per-packet memory corrupted.

Program received signal SIGABRT, Aborted.

However, there seems to be some strange corruption during the call to uat_new(), as seen in this gdb session as wireshark was starting up (with no capture file specified).

Any ideas?
