AttributeError: 'NoneType' object has no attribute 'get_display_info'

[CitronSorcier]

I got this error below:

Application Name: dupeGuru Picture Edition
Version: 2.10.1

Traceback (most recent call last):
  File "/usr/share/dupeguru_pe/qtlib/table.py", line 85, in data
    return self._getData(row, column, role)
  File "/usr/share/dupeguru_pe/qt/base/results_model.py", line 35, in _getData
    elif row.is_cell_delta(column.name):
  File "/usr/share/dupeguru_pe/core/gui/result_table.py", line 43, in is_cell_delta
    ref_info = self._group.ref.get_display_info(group=self._group, delta=False)
AttributeError: 'NoneType' object has no attribute 'get_display_info'

It happened after I've selected some files and sent them to Trash. This error occurred after I've tagged 'Delta values' on - it does not happen when Delta values are off.

Running Ubuntu 14.10 amd64.

It's not the first time I see this crash traceback, but with the extra details, it might be easier to find the root cause. Thanks.

I also got some very similar error with 'Delta values' on. Running on Linux Mint 17.1.

Same soft crash, only on Windows 7 Pro

Also after having sent some to trash and set delta values
also, in case it matters, I notice that one of the filenames has odd characters (exclamation points and curly braces) - maybe causing problems with metacharacter expansion?

I get the error in the (generic?) dupeGuru as well:

Got this today after deleting some files from the results.

I just got this today, running Arch Linux, using a version of DupeGuru sourced from the old website (the PKGBUILD in the AUR package is outdated). FWIW, the GUI shows much fewer rows than it should've after just performing a move on only a few sequential entries in the results, and I was using delta mode. I feel like it has to do with trashing the table after an action.

[cebtenzzre]

It seems as though the error occurs during a rebuild/redraw of the table (the rest of the entries, which seem to be the ones after the removed rows, are populated after closing the dialog), though that may not be significant.

I have the same error here, at Windows 10 x64 in Version: 4.0.4 RC

This should be a duplicate error that has been fixed in #905, recommend using the latest version at this point.
