This started happening maybe a week ago using the git version. No such problem
in Wine-Staging 6.17.
Most of the times Steam hangs when trying to log-in. Sometimes it gets past the
login window but it crashes/hangs when selecting certain command from the menu
e.g. Help->System Information or Check for Steam client update...
It often happens that the icons of the installed games in the library are
missing.

This bug doesn't occur when I omit the ntdll-Heap_Improvements patch from the
staging patchset.
Disabling esync doesn't help.
