|On my 32bit install the problem was slightly different as it was an 'NS_GetServiceManager' error:
/usr/lib/icedove/icedove-bin: symbol lookup error:
/usr/lib/icedove/components/libimgicon.so: undefined symbol:
Fix is BTS link :
However there is a typo so line should be:
LD_LIBRARY_PATH=/usr/lib/icedove LD_PRELOAD=/usr/lib/icedove/libxpcom.so icedove
My 64bit installs have not been impacted, (as yet!).
