Re: Trimming GtkEntry Text

[Micah Carrick <email micahcarrick com>]

(custom_command == NULL || sizeof(custom_command) <= 0)

custom_command is a gchar pointer, so, using sizeof simply gives you the 
size of the pointer, not the length of the string. 
"sizeof(custom_command) <= 0" will always be the size of a gchar pointer 
(4 bytes on my system).

If you're looking for the length of characters in the string, try using 
g_utf8_strlen() instead.
