IDon't,

I'm experiencing something that looks like some bug in busybox-power_1.19.3power2. But it is strange I have heard no one else about it.
Yesterday I noticed Python apps started losing their skin/buttons.

I traced it down to this:
For some reason, TMPDIR is not set (or unset) in the user shell (it is still set in the root shell).
Because it is not set, python starts looking in /tmp for the sapwood-engine entry (/tmp/sapwood-:0.0), but is is running in /var/tmp. First exporting TMPDIR to /var/tmp before starting solves it for that session.

When I reverted back to busybox-power_1.19.3power1, TMPDIR was set again. Upgraded to busybox-power_1.19.3power2 again, and TMPDIR was gone.
Setting the export in /etc/profile or ~/.profile does not work. The problem does not occur in the bash shell.

Edit: the issue is visable then a sh shell is opened in a existing shell. TMPDIR is not passed on to the next shell.
