If you get this Webilder error after updating to Jaunty as I did then you can fix as follows:
1. Backup the webilder.conf file:
cp ~/webilder/webilder.conf ~/webilder/webilder.conf.bak
2. Edit the webilder.conf file as follows - change line 20 from:
webilder.installation_date = time.struct_time(tm_year=2009, tm_mon=9, tm_mday=1, tm_hour=10, tm_min=34, tm_sec=56, tm_wday=1, tm_yday=244, tm_isdst=1)
to:
webilder.installation_date = (2008, 10, 26, 12, 25, 1, 6, 300, 1)
3. Save the file and retry adding the panel applet. All should work fine!
