Please describe the problem:
When Quicken exports a security list there can be an extra line in the QIF file for "investing goal" (aka an asset class).  This line starts with a G.  GnuCash currently ignores these - and rightly so because at the moment there is no concept of asset classes in GnuCash - but the importer prints the "unknown Security slot G" warning in the console for each security like this.

That looks messy.  Since we do know what the G line is for, I suggest adding logic to the importer to silently discard this info.  Or at least explicitly say what's happening rather than just using the generic "unknown slot" message.

Here is a sample:

!Type:Security
NVanguard 500 Index
SVFINX
TMutual Fund
GLarge Cap

Does this happen every time?
