I tested with EN-US Seamonkey 2.33.1 (German Language pack)  Gecko/20100101 Build 20150321194901 (Default Theme) on German WIN7 64bit:

1. Launch Emai client
   » opens with 1 active TAB, first account name shown in TAB header
2. Rightclick on first account ► Open in new TAB
   » new TAB opens with  first account name shown in TAB header
3. Right click most left TAB ► Close Tab
   » Tab closes
4. Right click most remaining last TAB ► Close Tab
   » onthing happens, although context menu item looked "active" (not 
     greyed out)

a) In Thunderbird this context menu becomes greyed out if onla 1 TAB 
   remains (TB offers more menu items than SM)
b) For more info see Wikipedia "Grayed out"

c) I wonder whether there might be a relation to "Bug 646609 - Always enable 
   Close Tab in the tab context menu"

Already REPRODUCIBLE with  DE  SeaMonkey 2.5  (Windows NT 6.1; WOW64; rv:8.0.1)  Gecko/20111121  Firefox/8.0.1   Build 20111121045514  (Classic Theme) on German WIN7 64bit, probably this problem has been in SM forever.
