change file.base twice will end with "Error: no writecb in Transform classh"

[nxf]

For some reason, I need change 'base' property of current file, after that I will change back old 'base' property. The code looks like this:

.pipe(tap(function(file){
   file.old_base = file.base;  
   file.base = file.base+"js/";  
}))
.pipe(something_otherprocessing())
.pipe(tap(function(file){
  file.base = file.old_base;
}))

When running, It will throw exception "Error: no writecb in Transform classh". when I remove the second tap calling, running will be ok, but I can not get the original 'base' property.

So any one can help me out?

@nxf What is the something_otherprocessing() doing? I tried to reproduce your exception in edea6ee tests/dest.test.coffee#L86 but to no avail.

Please test again with the latest release.

@nxf do you have a link to your old code that broke? If yes, can you post it here, so I can create a test-case?

I'm closing this for now, until I get further information.
