Saving config file fails b/c of bad files.path value

[RealRaven2000]

When trying to save configuration data, QuickFolders was throwing the following exception for one user:

[Exception... "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsIFile.initWithPath]"  nsresult: "0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH)"  location: "JS frame :: jar:file:///home/mglazer/.thunderbird/25pcu5tx.default/extensions/quickfolders@curious.be.xpi!/chrome/content/api/Utilities/implementation.js :: fileConfig :: line 25"  data: no] implementation.js:25:19
Uncaught (in promise) Error: An unexpected error occurred undefined
renderView: "TypeError: performance is null" viewer.mjs:5534:19

This was thrown at the following line:

    let dPath = prefs.getStringPref('files.path');
    if (dPath) {
      let defaultPath = Cc["@mozilla.org/file/local;1"].createInstance(NSIFILE);
       ...
   }

Apparently the (stored from earlier) files.path parameter must contain a valid path (even if the path doesn't exist) or be empty for this exception not to occur. Workaround would be to delete extensions.quickfolders.files.path from about:config.

here is a version with a fix

QuickFolders-mx-6.10.5pre19.zip

To try out this version, download the zip file and then drag it into Thunderbird Add-ons Manager (without extracting).
