@MohitMaliFtechiz With or without a trailing 0 sized chunk?

@MohitMaliFtechiz With or without a trailing 0 sized chunk?

@kelson42 With 0 size extra zim chunk.

[kelson42]

@MohitMaliFtechiz If you remove it, then it works?

[MohitMaliFtechiz]

@kelson42 Yes, if i remove the extra 0 size zim chunk then it starts saving the bookmark.

[kelson42]

Then clear duplicate of #3827

[MohitMaliFtechiz]

@kelson42 However, this is a duplicate of #3827 but we should handle the exception thrown by the libkiwix so that it would not crash our application until #3827 has not been fixed.

[MohitMaliFtechiz]

For the crashing scenario, I have placed a fix in #3862 so that application will not crash if libkiwix throw this type of errors, and updated the #3827 ticket description for this crash scenario.
