Error on search in text

[franklekens]

Ever since one of the latest versions (version 5, I don't know) I frequently get an error message when looking for a string of text in an e-book.

A number of search actions will work fine, but every now and then I get this message. I will see two hits listed in the bottom left corner, for instance. But when I want to click on the first of them, I get that message. Only if I close the book and re-open it can I perform the same search without errors.

Here's one such error message:

calibre, version 5.3.0
ERROR: Error in message handler: IndexSizeError: Failed to execute 'setBaseAndExtent' on 'Selection': The offset 153 is larger than the node's length (0).

Correction. Just now I had this same error. I didn't actually have to reopen the book. What I did was erase the search and performed some other search. That went fine. Then did this search again. Then I got the error again when I tried to click on the first result. Then I moved to the start of the book. Tried to click it again: now it worked.

It seems to have something to do with relative where you are in the book, but it is rather annoying and didn't use to happen with the old viewer, IIRC.

If you can open a bug report and attach a book where it happens along with a set of steps to reproduce it, it would help.
