I can't reproduce this, so I don't know the trigger, but from the backtrace:
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x000000000042fb9c in zoom_createZoom (w=0xd0d890,
call_data=call_data@entry=0x7fffb3cccdb0) at zoom.c:112
112 if (strcmp(gv_filename, "-")) {
Thread 1 (LWP 3049):
#0 0x000000000042fb9c in zoom_createZoom (w=0xd0d890,
call_data=call_data@entry=0x7fffb3cccdb0) at zoom.c:112
__s2 = 0x0
__result = <error reading variable __result (Cannot access memory at
address 0x0)>
__s2_len = 1
clearly strcmp(gv_filename, "-") is being called with gv_filename == NULL.
The attached check should alleviate the segfault, but perhaps something else
if wrong as well.
