Not a Gecko issue. New steps:
1. Install wine-1.5.3 package 2. Remove .wine dir 3. Rename /usr/share/wine/gecko -> /usr/share/wine/geckox 4. Run winecfg and refuse to install gecko 5. Check that there are no heap warnings WINEDEBUG=warn+heap winecfg 6. Install wine-1.5.4 package 7. Run WINEDEBUG=warn+heap winecfg and refuse to install Gecko. After that there will be cca 50x warn:heap lines
So it is independent wheter gecko is available or refused to install.
