Summary field populated with [nul] text

Question

Does somebody have an idea, why Open issues filter (or any other filter)  is showing text [nul] on some of the issues in summary field, although when opening Issue, there is valid text in summary field ie- for issue RZV-132 in summary is text "nova ideja - cards"

Sounds like it was trying to add something into the summary.  Glad you found it!

update: i found out that problem was in custom workflow for some other project - custom script used at transition "create" was messing somehow with all other projects. Sadly i dont have documented what was in custom code before i removed post function with custom script code.

Here it is..although its visible that when i clik and open issue RZV-123 there is no visible [nul] text nor in summary field, nor in Open issues filter...by clicking on issue, the [nul] part dissapears.

Simply by changing "Order by priority" sort ascending/descending [nul] randomly reappears on different issues,
