1128680 - Within Activity Manager window, a "Null" Shows above activity blocks , while indexing

Status: RESOLVED DUPLICATE of bug 492953

(Thunderbird :: Untriaged, defect)

Description

[john]

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20150122214805

Steps to reproduce:

Using 31.4, and looking at the activity manager

Not sure why this happens, but above the detail blocks, and below the title bar, the word "Null" appears -- during the reindexing I initiated.

It appears in a place where one might expect a drop down list to populate (but none does when hovering or clicking on the "Null").

When the reindex finally ended, the "Null" disappeared...
