Description

I want to loop over the following code in an IJulia notebook:

using Images,FileWatching
event = watch_file("test.png")
if event.timedout
    display("timeout")
end
display(load("test.png"))

The first execution works as expected, however, during the second execution I get the following error message

No applicable_loaders found for UNKNOWN

Stacktrace:
 [1] error(s::String)
   @ Base ./error.jl:33
 [2] applicable_loaders
   @ ~/.julia/packages/FileIO/40aie/src/loadsave.jl:11 [inlined]

 [7] include_string(mapexpr::typeof(REPL.softscope), mod::Module, code::String, filename::String)
   @ Base ./loading.jl:1094

and after executing the code yet another time additionally the following

┌ Error: There was an error in magic function detect_rdata.

Research direction

Reproduce the repeated IJulia notebook execution using the code and versions in the report. Start with FileIO/src/loadsave.jl and FileIO/src/query.jl, especially the stack-trace locations, and trace how the watched file is detected after the first load. Done means repeated executions load test.png without the UNKNOWN loader error or detect_rdata EOF warning.
