SIGABRT backtrace

I think the important part of the stack trace is in gam_listener.c:106:

100 #ifdef ENABLE_INOTIFY
101     if (gam_inotify_is_running() && (!gam_exclude_check(path))) {
102         gam_fs_mon_type type;
103 
104         type = gam_fs_get_mon_type (path);
105         if (type != GFS_MT_POLL)
106             gam_subscription_free(sub);
107     }
108 #endif

This shouldn't be reached unless the inotify backend has started successfully.

Looking at inotify-helper.c:90:

90         initialized = TRUE;
91 
92         result = ip_startup (ih_event_callback);
93         if (!result) {
94                 g_warning( "Could not initialize inotify\n");
95                 G_UNLOCK(inotify_lock);
96                 return FALSE;
97         }

it seems that initialized is set TRUE even if the start up fails.

I've tested a patch which changes this and it works for me. I'll attach it.

Patch to move initialized=TRUE

This patch moves initialized=TRUE to after the test of the return value from
ip_startup. It also makes similar changes with calls to inotify_init and
ik_startup.

Fixed in gamin-0.1.8-5.fc7 and upstream.
