I was trying to get acquainted with julia’s PyPlot library. I tried

```julia
using PyPlot;
imshow(rand(30, 30));

```

but I get the following error message

```julia
error in background error handler:
out of stack space (infinite loop?)
    while executing
"::tcl::Bgerror {out of stack space (infinite loop?)} {-code 1 -level 0 -errorcode NONE -errorinfo {out of stack space (infinite loop?)
    while execu..."
error in background error handler:
out of stack space (infinite loop?)
    while executing
"::tcl::Bgerror {out of stack space (infinite loop?)} {-code 1 -level 0 -errorcode NONE -errorinfo {out of stack space (infinite loop?)
    while execu..."

```

The message also happens to repeat again and again and the execution thread cannot be broken.

Could you tell me what is going wrong ?
