Opening account in gnucash

[Aaron Maxwell]

I'm running Gnucash version 1.8.4 on Debian.  I have three accounts: 
'Checking', 'Imbalance-USD', and 'Opening Balances'. I am able to open 
the last two just fine, but can't open the checking account. I click 
the 'Open' button when the account is selected, and Gnucash does not 
respond in any apparent way. (i.e., no error message - just silently 
fails).

'Checking' is of account type 'Bank'.  If I add another bank-type 
account, I am able to open it just fine (including if I record 
transactions in it).  

Incidentally, this issue is present in one of the distributed example 
XAC files: taxreport.xac.gz.  If you invoke gnucash with this XAC file, 
the account  'Assets->Bank->Checking One' can't be opened on my system, 
but 'Checking Two' is openable.  (I've put this file up at 
http://redsymbol.com/taxreport.xac.gz ).

Anyone else experienced this, or have ideas for what I can do?  I've 
included the versions of each of gnucash's dependencies on my system 
below.  (These are Debian package versions: x.y.z-nn.  The x.y.z refers 
to the version of the source; the n is a package version.)

Thanks, 
Aaron
