What I've done sometimes in debugging is to change that error to a
warning in the getNamespace() function, and add some tracing code to the
serialization code to print the names of objects as they are loaded.
(This goes in ReadItem in src/main/serialize.c.)
I wouldn't expect Liviu to make those changes, but perhaps a "verbose"
option could be added to load(), so that it could be available to users.
I have added this in R-devel. The format of the printed output may well
change before this is ever released, but it should be enough to identify the
bad item already.
You'll need a build of R-devel from r62658 or newer to see this. Then
load("/tmp/a.rda", verbose=TRUE)
will print the names of objects as they are read (the names are read after
the attributes and before the value). If you want to see reams of mostly
useless information, you can try verbose=n (for some number n=2 or more);
this prints names and component numbers to a greater depth.
Thank you for adding this in R. I will likely test this feature when
it gets released.
That will be about a year from now...
