I think the odd reason is that both eth0 and wlan0 would be on the same
network, i.e. 192.168.2.0. If you don't have your eth0 connected, the
network seems to be unreachable because data are sent on either eth0 or
wlan0 but not on both at the same time. That is the disadvantage of
static entries if your hardware connection isn't static. You have to
enable / disable the interfaces manually if they aren't connected.

Then you didn't try to use networkmanager or wicd lately, they don't
need static entries in the interfaces file. And they can handle
switching wired/wireless more or less automatically.

At least it is always interesting to see how others have solved their
network problems. Fortunately Bruce seems to have his machine working in
the meantime.
