Summary	0036969: Unknown category error in the MantisGraph plugin.
Description	When viewing the `issues_trend_bycategory_table.php` page of the MantisGraph plugin, an error of an unknown category is displayed. I discovered this bug while debugging the DateTimePicker inside plugin.
Additional Information	This is because the `category_get_name()` function is being called for a non-existent category ID.
Tags	No tags attached.
