We had an issue like that Marcelo, It was a while ago but I am pretty sure it was becasue of an issue with Application Preferences. For the affected users go to Application Preferences - Incident Management tab, under the overview colsole section look at the Role field and see if it is set to Assignee. When the Show field is set to "Assigned to My Selected Groups" or "Assigned to all my groups" Assignee is not a valid entry. We changed it to Assigned Group for the users and it resolved the issue.
I'm currently looking at it in 8.1 and there still looks to be some issues in this area as the fields populate with an ID and not a name in some cases.
