Invalid editor created by provider

Hi,

recently I am getting bug reports that state:

com.intellij.diagnostic.PluginException: Invalid editor created by provider net.seesharpsoft.intellij.plugins.csv.editor.table.CsvTableEditorProvider

The provided stacktrace doesn't hint to anything useful for me:

The plugin is actually providing two editors: A text editor and a table editor for CSV files. The bug reports are for the table editor provider only so far, but I don't know what needs to be changed to fix it. Any suggestions?
