GnuCash Price Editor

[w8]

Running GnuCash 2.6.0 built 29Dec2013 from git rev 38a0d33+ on Windows 7.
For info -  prices downloaded 01Feb14 challenge human readability/clarity.
example - price appears as '58 + 50000/3333333333' - Image attached
Previous month price shows as '57.190000'
Appears to me to be a format mix up since the account balance is correct.
Could be I need to correct a setting or reinstall.
Ideas??
