steampunk333 has asked for the wisdom of the Perl Monks concerning the following question:

For my html script, I'm trying to call a perl script using a form action, as seen below at line 157. However, I keep getting the error message "(process:2754): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed" whenever I try to use the form, which is supposed to return the results from the perl script(shown below the html). Can anyone explain to me what I'm doing wrong, and how to fix this?
