Application crashes when starting frame exceeds a certain value

This might be related to #3, but let us assume other entries in the File Info are correct.
For the same test file, it is supposed to be 60-second long. But when I set the starting frame to be 30000, which corresponds to 19.66 seconds, provided that points per frame are 1024, the Qt application crashes if click on the Plot button. The number of frames I try to plot is merely 200.
The error message is ValueError: cannot reshape array of size 0 into shape (200,1024).
It works fine for small starting frame numbers.
yes, the entries in the files are correct. yes, that is a similar issue. you must always care that there is enough "room" up there. This is a GUI only issue, just do not move the bar up there. This does not happen in the library.
I'm a bit concerned that the application crashes even if there are still plenty of data left in the file.
only if you choose the starting point such that the combination of lframes and nframes is larger than what is left, then it crashes. for now, you can avoid it by just deliberately not choosing a combination that goes over the edge. the GUI application is otherwise stable.
after a current fix on the iqtools library this issue should not happen any more. This has been cured by proper error handling on the library level. in the IQGUI this will be captured in a try-except scope
