Core Analysis

[edscott wilson garcia]

Solaris is very picky about stdio functions with NULL or uninitialized
variables. The line that croaks is:
g_snprintf(caption, sizeof(caption), "%s: %s",tl->options.tooltip, s);

Probably tl->options.tooltip is not a valid memory location. My guess is
that the triggerlauncher in question has no tooltip defined, and when tl
is allocated, options.tooltip is not initialized to "" (initializing to
NULL will cause a crash in Solaris).

If you define a tooltip when adding the triggerlauncher does it crash as
well?
