thanks full error log , github repro.

the blank trace error message confusing me...

but i'm guessing error caused fact our standard table view cell wrapper creates imageloader default - see https://github.com/slodge/mvvmcross/blob/v3/cirrious/cirrious.mvvmcross.binding.touch/views/mvxstandardtableviewcell.cs#l57

i'm guessing trace somehow coming https://github.com/slodge/mvvmcross/blob/v3/cirrious/cirrious.mvvmcross.binding/views/mvxbaseimageviewloader.cs#l30

this imageloader uses downloadcache plugin in turn uses file plugin. (it further needs text serializer json plugin if want persist images on disk more permanently).

if don't want images in app - don't want plugins - doesn't can avoid problem , continue using standard cell without changing source.

if wanted workaround problem:

1 create own standard table cell wrapper (based on https://github.com/slodge/mvvmcross/blob/v3/cirrious/cirrious.mvvmcross.binding.touch/views/mvxstandardtableviewcell.cs#l57) 2 use create custom cell. 3 register dummy/empty service satisfy imvximagehelper<uiimage> - work don't solution.

if think serious problem should provide core fix for, please log issue on github/slodge/mvvmcross.

in real apps don't tend use standard cells , tend need downloadcache , file plugin - don't come across common problem in work.
