With v0.11 whereami (on nokia E65) crashes out sometimes, phone resets other times. The E65 has bluetooth stability problems I think. I have seen phone do this with other bluetooth and not whereami. I did not lose .gpx info with crashes. I used up all memory on phone one time and lost last .gpx trace I had done. oops! Check your kids haven't been snapping tons of photos with your phone before OSMing!
With v0.13a after an initial .gpx collect (and maybe GSM cellids) I have an issue with whereami.db :( Need to follow instructions in FAQ: http://www.symbianos.org/faq/r=projectlink%3D47 The .db is not fully corrupt though. maps load fine. When I flip into named items view whereami crashes out.
