Without ~/.purple/plugins/libskypeweb.so plugin pidgin run properly

Strange behavior...

I check ~/.purple/accounts.xml file and cut "<account>...</account>" section with "prpl-skypeweb" protocol that like this:

    <account>
        <protocol>prpl-skypeweb</protocol>
        <name>SECRET_LOGIN</name>
        <password>SECRET_PASSWORD</password>
        <alias>SECRET_ALIAS</alias>
        <settings>
            <setting name='use-global-buddyicon' type='bool'>1</setting>
            <setting name='show-typing-as-icon' type='bool'>0</setting>
            <setting name='last_message_timestamp' type='int'>1516874150</setting>
            <setting name='show-typing-as-text' type='bool'>0</setting>
            <setting name='' type='bool'>0</setting>
            <setting name='buddy_icon_timestamp' type='int'>0</setting>
        </settings>
        <settings ui='gtk-gaim'>
            <setting name='auto-login' type='bool'>1</setting>
        </settings>
        <current_error/>
    </account>

and save file ~/.purple/accounts.xml then start pidgin with ~/.purple/plugins/libskypeweb.so plugin - pidgin run properly.

After I close pidgin and paste back <account>...</account> in ~/.purple/accounts.xml and start pidgin with ~/.purple/plugins/libskypeweb.so plugin - pidgin run properly. But my skype contact list disappear from group "My skype alias" and appeared in group as named "Skype" - I had to manualy move back my skype contacts from "Skype" to "My skype alias".

After this operations I again look in to ~/.purple/accounts.xml and now skype "<account>...</account>" section present as:

    <account>
        <protocol>prpl-skypeweb</protocol>
        <name>SECRET_LOGIN</name>
        <password>SECRET_PASSWORD</password>
        <alias>SECRET_ALIAS</alias>
        <statuses>
            <status type='Online' name='В сети' active='true'>
                <attributes/>
            </status>
            <status type='Away' name='Отошёл' active='false'>
                <attributes/>
            </status>
            <status type='Busy' name='Не беспокоить' active='false'>
                <attributes/>
            </status>
            <status type='Hidden' name='Невидимый' active='false'>
                <attributes/>
            </status>
            <status type='Offline' name='Не в сети' active='false'>
                <attributes/>
            </status>
        </statuses>
        <settings>
            <setting name='use-global-buddyicon' type='bool'>1</setting>
            <setting name='show-typing-as-icon' type='bool'>0</setting>
            <setting name='last_message_timestamp' type='int'>1481192134</setting>
            <setting name='show-typing-as-text' type='bool'>0</setting>
            <setting name='' type='bool'>0</setting>
            <setting name='buddy_icon_timestamp' type='int'>0</setting>
            <setting name='refresh-token'/>
        </settings>
        <settings ui='gtk-gaim'>
            <setting name='auto-login' type='bool'>1</setting>
        </settings>
        <current_error/>
    </account>

Now pidgin with ~/.purple/plugins/libskypeweb.so run fine. Strange bug
